How to Make an Easy Crochet Granny Square Phone Bag – Step by Step
A granny square phone bag is stylish, functional, and beginner-friendly. Using colorful yarns and simple stitches, you can make a compact bag perfect for carrying your phone, keys, and small essentials.
Materials Needed
- Yarn: Medium-weight cotton or acrylic yarn in 2–3 colors
- Crochet Hook: 4–5 mm (check yarn label)
- Scissors
- Yarn Needle for weaving in ends
- Optional: Button, snap, or Velcro for closure
Basic Crochet Stitches Used
- Chain (ch) – for foundation
- Slip Stitch (sl st) – to join rounds
- Single Crochet (sc) – for sturdy edges
- Double Crochet (dc) – main stitch for granny squares
- Cluster Stitch: 3 dc together (common in granny squares)
All stitches are beginner-friendly.

Step 1: Crochet Granny Squares
- Start with a magic ring or chain 4 and join to form a ring.
- Round 1: Chain 3 (counts as first dc), 2 dc into ring, chain 1, repeat 3 more times (total 4 clusters), join with sl st.
- Round 2: Slip stitch into first chain-1 space, chain 3, 2 dc in same space, chain 1, 3 dc in next chain-1 space, chain 1, repeat around, join with sl st.
- Round 3: Repeat the same pattern in each chain-1 corner space until the square reaches desired size for your phone bag (usually 10–12 cm per square).
Make 2 granny squares of the same size: one for the front and one for the back.
Step 2: Join the Squares
- Place squares together with wrong sides facing inward.
- Use single crochet or slip stitch to join three sides, leaving the top open for the bag.
- Keep stitches tight for durability.
Step 3: Create the Bag Edge
- Single crochet evenly around the top edge for a clean finish.
- Optional: Add a few rounds of sc or hdc for reinforcement.

Step 4: Make the Strap
- Decide the desired strap length.
- Chain enough stitches for the strap length.
- Attach the chain to the opposite side of the bag using single crochet.
- Work one round of sc along the chain for sturdiness.
Alternative: Make two straps for a mini crossbody style.
Step 5: Add Closure (Optional)
- Button: Sew a button on the front and make a chain loop on the top flap.
- Snap: Attach a snap for convenience.
- Velcro: Sew a small Velcro piece to keep the bag closed.
Step 6: Finish the Bag
- Fasten off the yarn and weave in all loose ends.
- Optional: Decorate with tassels, beads, or small crochet flowers for a cute touch.
