If you're looking for a beginner-friendly crochet bento bag pattern that folds flat, holds your food containers securely, and looks great while doing it, this is it.
Chain 3 (counts as first double crochet), then work 2 double crochets into the ring. Chain 2. Repeat the sequence (3 double crochets, chain 2) three more times around the ring. Slip stitch to join.
For each round, work 3 double crochet clusters into each side space, and (3 dc, ch 2, 3 dc) into each corner space. This means each corner has two clusters separated by the chain-2 space.
Continue repeating rounds until your square measures about 8.5–9 inches across.
Fasten off and make a total of three granny squares.
Layout and Assembly
Lay the three squares out in front of you so they form two diamonds touching at their corners, with the third square below them touching the full side of each top square.
Fold the two top squares inward so their outermost points meet in the center, forming two triangles.
Next, fold the bottom square’s tip upward to the center, creating a third triangle pointing toward the middle. You should now have three triangular flaps all converging at the center.
Sew or seam the edges where the two top squares touch the bottom square. Work carefully around each side edge until all the edges of the bottom square are attached to the sides.
Leave the open edges untied so they can be tied together to close the bag.
Tip: If your granny squares feel too small to tie comfortably, simply add more rounds to make them larger. This will require extra yarn, so plan accordingly.
Optional Handle
To add a handle instead of ties, chain 42. In the third chain from the hook, double crochet 40 stitches. Chain 2 and turn, then double crochet 40 stitches across. Fasten off
Attach the handle by sewing each end to the top corners of the folded sides of the bag.
Notes
Use 100% cotton yarn – It’s strong, washable, and perfect for holding heavier items.
Block your squares – Helps them lay flat and match in size for easier assembly.
Fold and pin first – Shape the bag before seaming to ensure alignment.
Take your time on corners – Neat corners improve structure and appearance.
Perfection isn’t required – Cotton has give; slight size differences are okay.
Test with weight – Load it lightly before finishing to check balance and tension.
Not lining it? – Weave in ends securely to prevent wear and unraveling.
