Sew a Collecting Bag for Children – An Easy DIY Idea for Little Holiday Treasures
A small fabric bag for shells, stones, feathers and drawn memories — quick to sew, lovingly designed and perfect for holidays, walks and little discovery adventures.
Some holiday treasures are so small that they later disappear between jacket pockets and suitcases.
A shell from the beach.
A particularly smooth stone.
A feather that was lying in the wind.Or something only the children desperately wanted to take home, because for one small moment it suddenly mattered.
This little fabric bag gives those tiny finds their own place — while you are out and later at home.
You only need a little fabric and a ribbon or cord. And from something very simple, a small companion for holidays, walks and discovery adventures begins to take shape.
A bag for small things.For big memories.And for everything children’s eyes find along the way, long before we adults even notice.
Why a Collecting Bag for Children Is Such a Lovely Idea
Shells, stones and small finds are often exactly the things children most want to bring home from a holiday. A little handmade bag gives these treasures their own place — while travelling and later at home. I love this idea because it is practical, and at the same time it preserves something very tender.
Because children collect differently than we do.
They do not simply see a stone.
They see the stone from the path to the sea.
Not simply a shell.
But the shell from that morning when the wind was still cool.
Not simply a ticket.
But a little memory that wants to stay.
A collecting bag for children helps these tiny things not simply vanish somewhere. It turns small objects into small stories. And the loveliest part: the bag is quick to sew, can be made from fabric scraps and can be used again and again — on holiday, in the forest, by the lake, at the playground or on a slow summer walk.
Materials: What You Need for the Collecting Bag
For this simple fabric bag, you only need a few materials:
a piece of fabric, for example cotton, optionally coated cotton for more resistance, as the outer fabric
muslin or another soft fabric as lining
a ribbon, cord or pretty cotton tape
sewing thread
fabric scissors or rotary cutter
pins or fabric clips
two small metal eyelets for the cord
sewing machine
optional small label, iron-on motif or fabric scrap for a heart, star or little mark
The fabric does not have to be new. A leftover piece, an old shirt, a worn cloth or a piece of bed linen can work beautifully. Especially for little holiday treasures, the bag may be simple, soft and uncomplicated.
Natural colors, delicate stripes or small patterns look especially lovely. But even a plain light-colored fabric can feel magical — especially once shells, stones or little drawings begin to live inside.
What Size Works Well for a Children’s Collecting Bag?
The bag should be big enough to hold a few small finds, but small enough for children to carry easily.
A practical finished size is about:
20 x 15 cm
For younger children, the bag can be a little smaller. For older children or longer holidays, it may be slightly bigger.
The important thing is that it does not become too heavy. Sometimes one single stone is enough. Not everything that is found needs to be collected — often a small selection is even more beautiful.
How to Sew a Collecting Bag: Simple Step-by-Step Tutorial
Step 1: Cut the Fabric
First, cut your fabric pieces.
For a bag of about 20 x 15 cm, you will need:
one rectangle of outer fabric: 47 x 17 cm
one rectangle of lining fabric: 47 x 24 cm
one round base from outer fabric: 17 cm diameter
one round base from lining fabric: 17 cm diameter
You can, of course, adjust the size. For a small shell bag, you may need less fabric; for larger holiday treasures, the bag may be a little wider.
Depending on the fabric, iron interfacing onto the back of the outer fabric and onto the upper part of the lining fabric, which will later form the drawstring channel. This gives the bag a little more structure and stability, while still keeping its soft, light shape.
Step 2: Prepare the Upper Edge and Drawstring Channel
Place the outer fabric rectangle and lining fabric rectangle right sides together and sew them together along one long edge. This seam will later become the upper edge of the bag, where the cord runs through.
If you like, you can topstitch the edge close to the seam afterwards. This looks neat and helps the upper edge sit nicely later.
Now attach two small eyelets in the center of the lining fabric. The cord will later be guided through these. Make sure the eyelets are firmly attached so they stay stable when the bag is opened and closed.
Optional: Sew on a Patch or Small Motif
If you would like your collecting bag to have a special detail, this is a lovely moment to add a small patch to the front.
For mine, I used a piece of lining fabric, strengthened it with interfacing, sewed it right sides together, turned it, then ironed it onto the outer fabric and topstitched it close to the edge.
Onto this patch, I added an iron-on transfer with a little frifri motif.
This gives the bag a tiny story even before the first outing — and turns it into a very personal companion for shells, stones, feathers and holiday memories.
Step 3: Close the Sides and Place the Cord
Now fold the sewn fabric pieces right sides together so that outer fabric lies on outer fabric and lining lies on lining.
Close the side seams. Leave a small turning opening of about 7 cm in the lining fabric. This creates a long tube made from outer bag and lining.
To make things easier later, you can already place the cord through the prepared drawstring area now. Make sure the cord ends lie on the right side of the fabric.
Secure the beginning and end of the seams well so everything stays stable.
If your fabric frays a lot, you can finish the edges with a zigzag stitch.
Step 4: Insert the Round Bases
Now the outer bag and lining receive their round bases.
First, pin the round base from outer fabric right sides together to the lower end of the outer fabric tube. Sew it slowly all the way around.
Then repeat the same step with the round base from lining fabric on the lining part.
Take your time with this step. Round bases need a little patience while sewing, but they do not have to be perfect. Small irregularities will hardly be visible later — and especially with a collecting bag for children, everything may stay a little alive and handmade.
If the base does not fit, adjust the side seam if needed by sewing it a little narrower.
Step 5: Turn and Finish the Bag
Carefully turn the bag through the opening in the lining fabric.
Shape the outer bag and lining nicely, then place the lining neatly inside the outer bag. Close the turning opening by hand or close to the edge with your sewing machine.
Now topstitch once around the upper drawstring area. This helps the edge sit neatly and keeps the cord nicely in place.
If you like, you can add two wooden beads to the cord ends and tie knots at the ends.
Now the bag can be pulled closed.
A small moment children often love:open, close, open again, close again.
Step 6: Add a Personal Detail
At the end, you can make the collecting bag even more personal.
Maybe you sew a small label onto the hem. Or add a little heart cut from fabric. Or a small star. Or write on the bag with fabric paint.
I especially love small details that are not too loud: a heart near the lower edge, a tiny piece of contrasting fabric, a ribbon in a favorite color.
This turns a simple fabric bag into a bag that belongs to exactly this child.
A little place for finds.And for memories that are allowed to stay.
What Can Go Into the Collecting Bag?
The little collecting bag is meant for things that become meaningful along the way.
For example:
one chosen stone
a shell
a feather
small nature finds that are allowed to be taken
an entrance ticket
a tiny note
a drawn memory
a pressed leaf, if it is allowed
a little holiday photo
one word that remembers the day
I especially like it when not everything goes into the bag, but only a few selected treasures.
Maybe at the end of an outing, you ask:
Which find may come with us today?
Which moment belongs in the bag?
What would we like to keep?
This turns the bag into more than a place for collecting. It becomes a small ritual.
Not Every Treasure Needs to Come Home
Not everything children discover may or should be collected.
Some natural finds belong where they are. In certain landscapes, parks, protected areas or beaches, collecting may not be allowed or may not be a good idea. And sometimes it is simply more beautiful to leave something where it was found.
Then something else can go into the bag instead:
a small photo,
a quick drawing,
a note with one word,
an entrance ticket,
a little piece of memory.
Maybe your child draws the special shell that had to stay on the beach. Or you write on a small note:
the smooth stone by the water
the feather in the wind
the big tree near the picnic
In this gentle way, a child learns: remembering does not always mean owning. Sometimes a treasure may stay where it is — and still travel onward with us.
A Little Idea for Home: Sorting Holiday Treasures
When you are back home, you can open the collecting bag together.
Not quickly.
But slowly.
What was this again?
Where did we find this stone?
Why did this exact shell need to come home?
Which drawing belongs to which day?
You can place the finds in a small bowl, fill them into a holiday jar or glue them into an album together with photos. Maybe the bag stays filled and goes into a memory box.
Especially lovely: a small fabric scrap from the bag can be glued into the family album. This way, the bag itself becomes part of the memory.
Letting Children Take Part
Children can be wonderfully involved in this small sewing project.
They can choose the fabric. Pick the ribbon. Cut out a heart. Think about what should go on the label. And, of course, decide which treasures may later go inside.
When children help design their collecting bag, it becomes more than a practical pouch. It becomes their own little companion.
Maybe they call it a shell bag, stone pouch, holiday bag, finders’ bag or treasure bag.
Whatever name it receives — it receives a story.
Which Outings Is the Collecting Bag Good For?
The collecting bag is not only for summer holidays.
It is lovely for: walks in the forest, days by the sea, trips to the lake, picnics in the park, visits to an open-air museum, weekends with grandparents, small walks through the neighborhood.
Sometimes one afternoon outside is enough for children to find something that matters to them. A leaf. A stone. A piece of bark, if it may be taken. Or simply a sentence they do not want to forget.
What Belongs on the First Outing with the Collecting Bag?
When the bag is finished, it may go outside.
For a little outing, you often do not need much: a water bottle, a light sweater, a small snack, maybe a notebook, a pencil, and the collecting bag for little holiday treasures.
For grown-up companions, the Dandelion Backpack can be a lovely fit — with space for water, snacks and all the little things that need to come along. In the frifri Summer Collection, you will find gentle companions for days like these outdoors: light in feeling, practical in everyday life and filled with motifs that feel like meadows, wind and little stories.
The backpacks are, of course, not a necessary part of this DIY. But sometimes it is lovely when the grown-ups also have a companion that leaves room — for everything a summer day may bring.
Little Design Ideas for Your Fabric Bag
You can leave the collecting bag very simple or decorate it lovingly.
Beautiful ideas include:
a small heart near the lower edge,
a sewn-on label,
an embroidered initial,
a small piece of lace ribbon,
a fabric scrap in a contrasting color,
a stamped word such as “summer,” “sea” or “finds.”
Children can also decorate the bag with fabric markers. Maybe they draw a shell, a sun, a little path or a symbol for the holiday. If you have more than one child, each child can have their own bag. This way, each little treasure collector becomes completely different.
My Conclusion: A Small Bag for Big Memories
To sew a collecting bag for children is an easy DIY idea that does not need much.
A piece of fabric. A cord. A few seams. And the willingness to take small things seriously.
The finished bag accompanies children through holidays, walks and little discovery adventures. It gives shells, stones, feathers, drawings and notes a place — and reminds us that some treasures do not have to be expensive, large or perfect.
Some fit into a child’s hand.
Some are better left in nature.
Some travel home as a photo or drawing.
And maybe, at the end of summer, the bag lies in a small box, filled with what was allowed to stay.
