Materials Needed

Before you begin your crochet journey, gather these essential materials:

• Yarn: Worsted weight cotton or cotton-blend yarn in three colors:
  • Color A (Sand) – approximately 200g
  • Color B (Terracotta) – approximately 100g
  • Color C (Deep Rust) – approximately 100g
  Total: approximately 400g of yarn
• Crochet Hook: 5.0 mm (H-8) crochet hook, or size needed to obtain gauge
• Gauge: 16 single crochet (sc) x 18 rows = 4 x 4 inches (10 x 10 cm)
• Notions: Yarn needle for weaving ends, stitch markers, one wooden button (approximately 1 inch/2.5 cm diameter)
• Scissors for cutting yarn

Pro tip: Choose a cotton or cotton-blend yarn for durability and structure. The natural fibers will hold their shape beautifully and withstand daily use.

Step-by-Step Instructions

This backpack is worked in the round from the bottom up. The mosaic pattern is created using single crochet and front post double crochet stitches to form geometric diamonds. Take your time with the stitch transitions, and you'll be rewarded with a stunning, professional-looking result.

Base

Begin with Color A (Sand) to create a sturdy, circular base:

• Round 1: Make a magic ring, chain 1, work 8 single crochet (sc) into the ring, slip stitch (sl st) to join. (8 sc)
• Round 2: Chain 1, work 2 sc in each stitch around, sl st to join. (16 sc)
• Round 3: Chain 1, *sc in next stitch, 2 sc in next stitch*, repeat from * to * around, sl st to join. (24 sc)
• Round 4: Chain 1, *sc in next 2 stitches, 2 sc in next stitch*, repeat from * to * around, sl st to join. (32 sc)
• Round 5: Chain 1, *sc in next 3 stitches, 2 sc in next stitch*, repeat from * to * around, sl st to join. (40 sc)
• Round 6: Chain 1, *sc in next 4 stitches, 2 sc in next stitch*, repeat from * to * around, sl st to join. (48 sc)
• Round 7: Chain 1, *sc in next 5 stitches, 2 sc in next stitch*, repeat from * to * around, sl st to join. (56 sc)
• Round 8: Chain 1, *sc in next 6 stitches, 2 sc in next stitch*, repeat from * to * around, sl st to join. (64 sc)
• Round 9: Chain 1, *sc in next 7 stitches, 2 sc in next stitch*, repeat from * to * around, sl st to join. (72 sc)
• Round 10: Chain 1, *sc in next 8 stitches, 2 sc in next stitch*, repeat from * to * around, sl st to join. (80 sc)
• Round 11: Chain 1, sc in each stitch around, sl st to join. (80 sc)

Your base should now measure approximately 8 inches (20 cm) in diameter. If it's smaller, you may need to check your gauge and adjust your hook size accordingly.

Body (Mosaic Pattern)

Now we'll create the stunning mosaic effect. This section is worked in repeating rounds to form three beautiful bands of geometric pattern.

First Mosaic Band:

• Round 12: Chain 1, with Color A, sc in each stitch around, sl st to join. (80 sc)
• Round 13: Chain 1, with Color B (Terracotta), *front post double crochet (fpdc) around next stitch, sc in next stitch*, repeat from * to * around, sl st to join. (40 fpdc, 40 sc)
• Round 14: Chain 1, with Color B, *sc in next stitch, fpdc around next stitch*, repeat from * to * around, sl st to join. (40 sc, 40 fpdc)
• Round 15: Chain 1, with Color C (Deep Rust), *fpdc around next stitch, sc in next stitch*, repeat from * to * around, sl st to join. (40 fpdc, 40 sc)
• Round 16: Chain 1, with Color C, *sc in next stitch, fpdc around next stitch*, repeat from * to * around, sl st to join. (40 sc, 40 fpdc)
• Round 17: Chain 1, with Color A, sc in each stitch around, sl st to join. (80 sc)

Openwork Mosaic Section:

• Round 18: Chain 1, with Color A, *sc in next stitch, chain 1, skip next stitch*, repeat from * to * around, sl st to join. (40 sc, 40 chain-1 spaces)
• Round 19: Chain 1, with Color B, *sc in next chain-1 space, chain 1, skip next sc*, repeat from * to * around, sl st to join. (40 sc, 40 chain-1 spaces)
• Round 20: Chain 1, with Color B, *sc in next chain-1 space, chain 1, skip next sc*, repeat from * to * around, sl st to join. (40 sc, 40 chain-1 spaces)
• Round 21: Chain 1, with Color C, *sc in next chain-1 space, chain 1, skip next sc*, repeat from * to * around, sl st to join. (40 sc, 40 chain-1 spaces)
• Round 22: Chain 1, with Color C, *sc in next chain-1 space, chain 1, skip next sc*, repeat from * to * around, sl st to join. (40 sc, 40 chain-1 spaces)
• Round 23: Chain 1, with Color A, sc in each chain-1 space and sc in each sc around, sl st to join. (80 sc)

Repeat Rounds 12-23 two more times to create three complete mosaic bands. Each band will add approximately 2.5 inches (6.5 cm) to the height of your backpack.

Finishing the Body:

• Work even with Color A in single crochet for 4 rounds. This creates a clean, solid section at the top of the bag body. (80 sc each round)

Top Edging

This section creates the buttonholes that will secure your flap:

• Next Round: Chain 1, *sc in next 3 stitches, chain 2, skip 2 stitches*, repeat from * to * around, sl st to join. (This creates buttonholes – you'll have 16 buttonholes total)
• Next Round: Chain 1, sc in each stitch and 2 sc in each chain-2 space around, sl st to join. (80 sc)
• Fasten off and weave in the end.

Straps (Make 2)

These sturdy straps are worked flat and will be sewn to the back of the backpack:

• Row 1: With Color A, chain 8, sc in 2nd chain from hook and in each chain across, turn. (7 sc)
• Rows 2-60: Chain 1, sc in each stitch across, turn. (7 sc)
• Fasten off, leaving a long tail (approximately 12 inches/30 cm) for sewing.

Each strap will measure approximately 15 inches (38 cm) long. Adjust the number of rows if you prefer longer or shorter straps.

Flap

The triangular flap adds both function and style to your backpack:

• Row 1: With Color A, chain 26, sc in 2nd chain from hook and in each chain across, turn. (25 sc)
• Rows 2-10: Chain 1, sc in each stitch across, turn. (25 sc)
• Row 11: Chain 1, sc2tog (single crochet 2 together), sc in next 21 stitches, sc2tog, turn. (23 sc)
• Row 12: Chain 1, sc2tog, sc in next 19 stitches, sc2tog, turn. (21 sc)
• Row 13: Chain 1, sc2tog, sc in next 17 stitches, sc2tog, turn. (19 sc)
• Row 14: Chain 1, sc2tog, sc in next 15 stitches, sc2tog, turn. (17 sc)
• Row 15: Chain 1, sc2tog, sc in next 13 stitches, sc2tog, turn. (15 sc)
• Row 16: Chain 1, sc2tog, sc in next 11 stitches, sc2tog, turn. (13 sc)
• Row 17: Chain 1, sc2tog, sc in next 9 stitches, sc2tog, turn. (11 sc)
• Row 18: Chain 1, sc2tog, sc in next 7 stitches, sc2tog, turn. (9 sc)
• Row 19: Chain 1, sc2tog, sc in next 5 stitches, sc2tog, turn. (7 sc)
• Row 20: Chain 1, sc2tog, sc in next 3 stitches, sc2tog, turn. (5 sc)
• Row 21: Chain 1, sc2tog, sc in next 1 stitch, sc2tog, turn. (3 sc)
• Row 22: Chain 1, sc3tog (single crochet 3 together). (1 sc)
• Fasten off, leaving a long tail for sewing.

The flap will have a trapezoid shape that tapers to a point at the bottom, creating a beautiful triangular closure.

Assembly

Now it's time to bring all your pieces together:

1. Attach the straps: Position the straps on the back of the backpack, spacing them about 4 inches (10 cm) apart. Secure them at the top edge, placing the ends about 1 inch (2.5 cm) below the top edge. Sew firmly using the long tails you left, making sure to catch both the strap and the bag body securely.
2. Attach the flap: Center the flap on the back of the backpack, just below the top edge. The straight edge of the flap should align with the top edge of the bag. Sew it securely, making sure it aligns with the buttonholes on the front.
3. Attach the button: Position the wooden button on the flap so it aligns with the buttonholes. Sew it securely through both the flap and the bag body.
4. Weave in all ends: Using your yarn needle, carefully weave in all loose ends to give your backpack a clean, professional finish.
