🧵 Materials You’ll Need

To crochet a granny square phone bag, you will need the following supplies:

✂️ Tools:

Crochet hook: Size 4.0 mm (G-6) or 4.5 mm depending on your yarn
Yarn needle: For weaving in ends and sewing pieces together
Scissors

🧶 Yarn:

Worsted weight cotton or acrylic yarn (Medium #4): You can use multiple colors for a vibrant look or stick to one for a minimalist style.
- Example: Color A (main square), Color B (border), Color C (strap)

Optional:

Magnetic clasp or button for closure
Lining fabric and needle/thread (for extra durability)

📐 Finished Dimensions

The size of your phone bag depends on:

The number of granny squares
The size of each square
The phone size

For most standard phones, you’ll want the final bag to be at least:
Width: 4.5 to 5 inches (11.5 to 13 cm)
Height: 6.5 to 7.5 inches (16.5 to 19 cm)

You can either:

Use two large granny squares (front and back), or
Join four small squares (two per side)

In this pattern, we’ll use two large granny squares, approx. 5" each.

🔁 Step-by-Step: Crochet the Granny Squares

Here's a basic granny square pattern, worked in rounds. You can adjust colors per round or use one solid color.

Abbreviations (US Terms):

ch = chain
sl st = slip stitch
dc = double crochet
sp = space
st(s) = stitch(es)

🌸 Basic Granny Square Pattern

Round 1:

Start with a magic ring, or ch 4 and sl st into the first ch to form a ring.
Ch 3 (counts as dc), 2 dc, ch 2, (3 dc, ch 2) repeat 3 times into the ring.
Join with sl st to top of beginning ch-3. (You’ll have 4 clusters of 3 dc, and 4 corner ch-2 spaces.)

Round 2:

Sl st over to the next ch-2 sp. Ch 3 (counts as dc), 2 dc, ch 2, 3 dc in the same sp (corner made).
(3 dc in next sp between clusters), in next ch-2 corner: 3 dc, ch 2, 3 dc repeat around.
Join with sl st to beginning ch-3.

Round 3:

Continue as in Round 2, placing 3 dc in each space between clusters and working 3 dc, ch 2, 3 dc in each corner.

Round 4 (optional, for bigger square):

Repeat pattern, growing your square. Make sure corners are always: 3 dc, ch 2, 3 dc.

👉 Make two granny squares, each around 5" x 5". Add more rounds if needed to size them up.

🧵 Step-by-Step: Join the Squares

Once you have two granny squares, it’s time to assemble the bag.

Step 1: Align the Squares

Place the two squares wrong sides together, matching all edges.

Step 2: Seam Three Sides

You can join them using:

Slip stitch join through both layers (fast and easy)
Single crochet join (adds a nice ridge)
Whip stitch with a yarn needle (cleanest, nearly invisible)

👉 Leave the top open for the phone to slide in.

🧵 Step-by-Step: Add the Strap

You have a few options for the strap:

🪢 Option 1: Simple Crochet Strap

Attach yarn to one top corner of the bag.
Ch 100–120 (or until desired length, approx. 40–50 inches).
Attach to opposite top corner with sl st.
Turn and work sl sts or sc all the way back across the chain.
Fasten off and weave in ends.

🪢 Option 2: Braided or Twisted Cord

Cut 3 long strands (2–3x desired strap length), braid them tightly, and sew ends to bag corners.

🪢 Option 3: Use Ready-Made Strap

You can use a leather, chain, or canvas strap and attach with D-rings or sew directly to the bag.

✨ Optional Finishing Touches

🧲 Add a Button or Clasp

Sew a small button to the front and create a loop from chain stitches on the back flap (if you add one), or use a magnetic snap inside.

🪡 Line the Bag (Optional but helpful)

If you’re carrying small items like cards or coins, adding a fabric lining prevents stretching and protects the yarn.

Steps:

Cut a rectangle of fabric slightly larger than your bag.
Fold and sew edges inward.
Hand-stitch the fabric into the inside of the crochet bag.

🎨 Customization Ideas

Alternate colors every round for a rainbow look
Use scrap yarn for a boho style
Add a small granny square flap on top for closure
Add beads or fringe to the bottom for flair
Use mini granny squares for a patchwork effect

🧺 Care Instructions

Hand-wash or gentle cycle in cold water
Lay flat to dry
Avoid ironing unless lined with fabric

🏁 Final Thoughts

A granny square phone bag is not just a practical accessory—it’s a mini art project that reflects your creativity. It’s great for gifting, selling, or adding to your handmade wardrobe. Once you master the granny square and seaming, the possibilities are endless!
