What is this Crochet Phone Bag

A crochet phone bag sling is a small crossbody pouch designed to hold a phone and a few essentials, such as cards or keys. This version has a clean oval base, a tall single-crochet body for structure, a triangle-style flap, and a simple button closure. The long strap makes it comfortable for daily use, especially when you do not want to carry a full handbag.

Materials Section

• Optional: cotton blend for a softer feel
• Colors: 1 main color for the bag body, optional contrast for edging or flap border

Hook Size

• 3.5 mm to 4.5 mm, depending on yarn
  Tip: choose the smaller end of the range for tighter stitches and fewer gaps.

Closure

• 1 button (18 to 25 mm works well)
  or
• 1 magnetic snap for a cleaner finish (optional)

Tools and Accessories

• Tapestry needle for sewing and weaving ends
• Scissors
• Stitch marker (highly recommended)
• Optional lining fabric + sewing needle and thread

Abbreviations

• ch = chain
• sc = single crochet
• dc = double crochet
• sl st = slip stitch
• inc = increase (2 stitches in the same stitch)
• dec = decrease (2 stitches crocheted together)

Notes Before Starting

• Measure your phone first: width, height, and thickness. Your starting chain controls how wide the pouch will be.
• Keep stitches tight for structure. If you see holes, go down a hook size.
• Add the flap and strap at the end so you can adjust fit and placement neatly.
• Phone bags are simple beginner projects because they use basic stitches and repeatable rounds.

The pattern is worked in continuous rounds unless otherwise stated. Use a stitch marker to mark the first stitch of each round.

The sample size below fits many modern smartphones. For a larger phone, start with ch 15 instead of ch 13.

1) Base: Oval Base (worked around a chain)

Ch 13.

Round 1:
Sc in 2nd ch from hook, sc in next 10 ch, 3 sc in last ch.
Rotate and work into the other side of the chain: sc in next 10 ch, 2 sc in last ch.
Stitch count: 26

Round 2:
Inc in first st, sc in next 10, inc in next 3 sts (the curved end), sc in next 10, inc in last 2 sts (the other curve).
Stitch count: 34

Round 3:
Sc 1, inc, sc in next 10, (sc 1, inc) x3, sc in next 10, (sc 1, inc) x2.
Stitch count: 42

Round 4:
Sc around.
Stitch count: 42

Optional test: place your phone on the base. The base should be slightly wider than the phone so the sides can come up without pulling.

2) Body: Work Up the Sides

Round 5:
Back-loop-only sc around (this creates a crisp fold edge).
Stitch count: 42

Rounds 6 to 22:
Sc around.
Stitch count each round: 42

Adjust the height if needed: add or remove a few rounds so the phone sits fully inside, leaving about 2 to 3 cm of space for the flap to close.

Finish Round 22 with sl st. Do not fasten off if you want to start the flap immediately.

3) Flap: Triangular Flap (rows)

You will crochet the p fabric back and forth across the back of the bag opening. Choose a centered section of 14 stitches on the back.

Row 1:
Sc 14, ch 1, turn.
Stitch count: 14

Row 2:
Dec, sc 10, dec, ch 1, turn.
Stitch count: 12

Row 3:
Dec, sc 8, dec, ch 1, turn.
Stitch count: 10

Row 4:
Dec, sc 6, dec, ch 1, turn.
Stitch count: 8

Row 5:
Dec, sc 4, dec, ch 1, turn.
Stitch count: 6

Row 6:
Dec, sc 2, dec, ch 1, turn.
Stitch count: 4

Row 7:
Dec x2, ch 1, turn.
Stitch count: 2

Row 8:
Dec.
Stitch count: 1

Flap edging (optional, for a neat finish):
Ch 1, sc evenly around the flap edges (place 1 sc per row edge, and 2 sc at the tip if you want a sharper point). Sl st to finish.
Fasten off, weave in ends.

4) Button Loop

Join yarn at the flap tip.

Ch 10, then sl st back into the same point to form a loop.
If your button is thick, chain 12 instead.
Fasten off and weave in.

5) Button Placement

Close the flap and see where the loop lands on the front of the bag. Sew the button there using strong thread or yarn. Make multiple passes so it holds up to daily use.

6) Strap

Option A (simple and sturdy): chain + sc strap
Ch 170 to 200 (choose based on your height and preferred crossbody length).

Row 1:
Sc in 2nd ch from hook, sc across.
Stitch count: 169 to 199 (depends on your starting chain)

Fasten off, leaving long tails for sewing.

Option B (extra strong): make a second sc row back across the strap. This gives a thicker strap and reduces stretch.

7) Attach Strap to Bag

Sew the strap ends to the top edges of the bag opening, one on each side seam. Stitch firmly with repeated passes. Weave in tails inside the bag.

8) Optional Lining (Quick Method)

Cut fabric slightly smaller than the bag shape, sew side seams, then hand-stitch it inside. Keep stitches small and tidy, especially near the top edge and button area.

Step-by-Step Making Guide

Step 1: Gather materials

Pick cotton yarn, a matching hook, a button or magnetic snap, scissors, a stitch marker, and a tapestry needle. If you want lining, choose thin cotton fabric.

Step 2: Crochet base

Start with a chain and crochet around it to form an oval. This is the part that decides the width, so test it with your phone early.

Step 3: Build body

Work single crochet rounds straight up. Keep your tension tight so the bag stands up and does not sag.

Step 4: Make a flap

Crochet the flap in rows on the back side. Use decreases at both ends to form a clean triangle shape.

Step 5: Add a button

Make a chain loop at the flap tip, then sew the button onto the front where the loop reaches naturally.

Step 6: Create a strap

Crochet a long strap and reinforce it with a row of single crochet so it stretches less during wear.

Step 7: Assemble

Sew the strap ends securely to the bag sides. Double-check that the flap closes smoothly over the opening.

Step 8: Finishing

Weave in every end neatly, shape the bag with your hands, and do a final fit check with your phone and essentials.

Common Mistakes

• Using too large a hook, which creates holes and weakens the fabric
• Skipping the back loop only round, so the base edge looks messy
• Not testing the size with your phone until the end
• Sewing the strap with too few stitches (it can rip over time)
• Placing the button too high or too low, making the flap pull

Customization Ideas

• Add a contrast border around the flap edge
• Make a textured front panel with DC or a simple stitch pattern
• Add a small inner pocket (especially if you add lining)
• Use two colors: solid body, contrast flap and strap
• Add a tassel or charm to the flap tip for a cute finish

Conclusion

This crochet phone bag sling is one of those satisfying projects you can finish, use immediately, and remake in different colors. Try it in sturdy cotton, keep your stitches tight, and adjust the size to your phone for the best fit. If you make one, save your notes so the next one turns out even cleaner.
