Materials You Will Need
Gather everything first so you never have to stop mid-row and hunt for yarn.
- Sky blue worsted weight cotton or cotton blend: 520 yards
- White worsted weight cotton: 45 yards
- Rainbow colors: 12 to 18 yards each of red, orange, yellow, green, blue, and purple
- US G/6 (4.0 mm) hook, or size that hits gauge
- Yarn needle, stitch markers, scissors
- One button about 0.7 inches
- Optional: polyester fiberfill for the clouds, lining fabric, or a lightweight base insert
Paintbox Yarns Cotton Aran, Lily Sugar’n Cream, or Knit Picks Dishie all give crisp definition and hold up well. Soft acrylic works if you line the bag or use a slightly smaller hook for extra durability.

Gauge Information
Swatch before you dive in. Size matters on a backpack that needs to fit real kid stuff.
Single crochet should measure 14 sc by 12 rows = 4 inches. Open granny mesh aims for 11 granny groups and 11 open spaces equaling about 9.8 inches wide, with 10 rows measuring roughly 4 inches tall after light blocking. Make a 6-inch square in both fabrics, wash and dry it the same way you plan to treat the finished bag, then adjust your hook if needed.
Abbreviations and Special Stitches
Here is the short list so nothing slows you down.
- ch – chain
- dc – double crochet
- sc – single crochet
- sl st – slip stitch
Open Granny Mesh: Edge double crochet, then groups of three double crochets worked into the spaces from the previous row. The panels use 11 groups across with straight side edges.
Invisible Join: Cut the yarn, pull the tail through the last stitch, thread the needle under both loops of the first stitch, then back through the last stitch. Tighten gently for a seamless finish.
Standing Single Crochet: Make a slip knot, insert the hook, pull up a loop, yarn over and pull through both loops. Clean way to join yarn without a visible chain.
Building the Main Panels and Gusset
The front and back panels start with a short single-crochet band for structure, then switch to open granny mesh for that light, textured body. Chain 36, work a few rows of single crochet, then move into the mesh: edge double crochet plus eleven groups of three double crochets across. Continue the mesh until the panel reaches about 11.8 inches tall, then finish with a single-crochet row. Block lightly so the mesh opens evenly.
The side and bottom gusset is a long single-crochet strip that creates the depth. Chain 18 and work until the strip measures roughly 28.3 inches long and 4.8 inches wide. Edge it all the way around, placing two single crochets in each corner. This piece travels up one side, across the bottom, and up the other side without stretching.

Pocket, Flap, Straps, and Appliques
The front pocket is a simple single-crochet rectangle edged neatly and finished with a centered button. The top flap mixes a short single-crochet band with a smaller granny mesh section, then gets a full single-crochet border and a button loop at the center front.
Shoulder straps are long single-crochet strips edged for strength. The top handle is shorter and works the same way. Two drawstring cords thread through the upper mesh openings so the bag cinches closed from both sides.
The rainbow appliques work from the inner arc outward in single crochet, increasing at the curves so each color band sits smoothly. Make one large rainbow for the flap, one medium for the pocket, and three more for lower front and side accents. Clouds start with a small ring of double crochet, then a shaped second round that creates the classic puffy outline. Add a tiny bit of fiberfill under each cloud before sewing for extra dimension.

Assembly and Finishing
Mark the center tops of the front, back, and gusset. Pin the gusset around the front panel with right sides out and seam firmly. Repeat for the back. Sew the pocket centered on the lower front, leaving the top open. Attach the flap to the back top edge so it folds over cleanly. Secure the shoulder straps at the upper and lower back corners and place the handle between the strap tops. Reinforce every attachment point with a small square of stitching.
Weave the drawstrings through the top mesh in opposite directions and knot the ends. Pin all five rainbows first—large on the flap, medium on the pocket, and three accents across the lower front and sides—then sew them invisibly through the back loops. Weave in every end on the inside, splitting the tails through nearby stitches for security.
Steam or wet block lightly without over-stretching the mesh. Add a simple lining if you want extra structure. Sew the button last so the flap loop lands naturally when the bag is filled.

Care Instructions and Size Adjustments
Spot clean when possible. For cotton yarn, hand wash in cool water and reshape while damp. Dry flat with the bag lightly stuffed with towels so it keeps its shape. Remove any base insert or pouch before washing.
Need a different size? Add or remove three foundation stitches on the main panels for width changes. Add or remove mesh rows for height. Adjust the gusset chain length for depth. Hold the bag on the intended wearer before finishing the straps so the length feels right.

FAQ’s
How long does this backpack take to finish?
Most makers complete it in 10 to 14 relaxed hours. The mesh panels move quickly once the rhythm clicks. The rainbows and assembly add the cheerful finishing touches.
Can I use acrylic yarn instead of cotton?
Yes, but consider lining the bag or using a slightly smaller hook for better durability. Cotton holds its shape and washes more easily for kid use.
Do the clouds need stuffing?
A tiny bit of fiberfill makes them look puffy and dimensional. Without it they still look cute, just flatter.
What if my panels turn out different sizes?
Block them lightly and count the granny groups carefully. Each mesh row should have exactly eleven groups between the two edge double crochets.
Is this sturdy enough for everyday preschool use?
Yes, especially with firm cotton and reinforced strap attachments. A simple lining or base insert adds even more strength if the bag will see heavy daily wear.
