Dusty plum crochet phone sleeve with a small front pocket

A phone sleeve is a surprisingly good first practical crochet project.

You don't have to calculate complicated shaping or keep track of many stitch changes. For this version, we'll make one long rectangle, fold it into a sleeve, seam the sides, and add a small contrasting pocket.

The pocket is useful for something lightweight such as a note or cleaning cloth, but it also gives you a chance to practice attaching one crochet piece to another.

Best of all, we'll size the sleeve using your phone, rather than relying on one fixed stitch count.

Skill level: Beginner
Terms: US crochet terminology
Construction: Worked flat, folded and seamed
Main stitch: Single crochet
Sizing: Adjustable

Start With Your Phone, Not a Stitch Count

Before touching the yarn, put your phone on the table.

We're going to use it as our sizing guide.

Your finished crochet fabric should be slightly wider than the phone when folded around it, but not so loose that the device moves around freely.

Remove any unusually bulky accessories before measuring if you don't plan to use them with the sleeve.

This approach is useful because current beginner phone-pouch patterns also emphasize adjustable sizing rather than assuming everyone owns the same phone.

What You'll Need

Keep it basic:

  • Medium-weight smooth yarn
  • Crochet hook suitable for your yarn
  • Scissors
  • Yarn needle
  • Two stitch markers
  • One small button
  • Your phone for sizing

Use dusty plum for the main sleeve and warm oatmeal for the pocket if you want to reproduce our YarnSteps version.

A smooth yarn will make the individual stitches easier to identify.

Step 1: Crochet the Starting Chain

Make a foundation chain approximately as wide as your phone, with a little extra room.

Don't stretch the chain while measuring it.

Place it across the phone.

It should extend slightly beyond both sides.

This small amount of extra space will help accommodate the thickness of the device once the sleeve is assembled.

Beginner note

Avoid making the starting chain extremely tight.

If the chain is much tighter than the following rows, the bottom of your finished sleeve may pull inward.

Step 2: Make the First Row

Starting in the second chain from your hook, work:

1 single crochet in each chain across.

When you reach the end:

Chain 1 and turn.

Now work one single crochet in every stitch across again.

Chain 1 and turn.

That's essentially the rhythm for the main body.

Step 3: Build a Long Rectangle

Continue working:

Single crochet across → chain 1 → turn.

After several rows, place your phone beside the crochet.

You'll see a rectangular strip beginning to form.

Keep going.

Eventually, the rectangle needs to be long enough to travel:

up the front of the phone → around the bottom → up the back.

Don't seam anything yet.

We want to test the size first.

CHECKPOINT: Fold Before You Cut

This is the step I don't want you to skip.

Lay your phone over one half of the rectangle.

Fold the remaining half over it.

Check the top.

The phone should slide in and out without forcing the crochet, but the sleeve shouldn't have huge gaps around the sides.

Too short?

Add more rows.

Much too long?

Undo a few rows.

Too narrow?

Unfortunately, width comes from your starting chain. If it's considerably too narrow, restarting now will produce a much cleaner result.

That's why we checked the chain against the phone at the beginning.

Step 4: Seam the Two Sides

Remove the phone.

Fold the rectangle in half with the edges aligned.

Place a stitch marker through each side to stop the layers from shifting.

Thread a long yarn tail onto your yarn needle.

Sew one side from the bottom toward the opening.

Then sew the other side.

Try to pass through corresponding stitches on both layers so the edges remain reasonably straight.

Do not sew the top closed.

That's where the phone goes.

Step 5: Make the Contrasting Pocket

Now we'll add the feature that makes this design different.

Using warm-oatmeal yarn, make a small rectangle about half the width of the sleeve.

Work simple single crochet rows until the pocket reaches the height you want.

For the final row, we'll soften the top edge.

Across the top, alternate small groups of:

single crochet → half double crochet → single crochet

rather than making large decorative shells.

The result should be a subtle wave, not a dramatic scalloped border.

Fasten off, leaving a long tail.

Step 6: Attach the Pocket

Place the oatmeal rectangle on the lower front of the phone sleeve.

Make sure it's centered.

Use stitch markers to hold it temporarily.

Now sew:

Left side → bottom → right side.

Leave the upper edge completely open.

Check the inside afterward to make sure you haven't accidentally sewn through both the front and back of the phone sleeve.

That's an easy beginner mistake.

Step 7: Add a Simple Loop Closure

You could stop here, but a small closure gives the sleeve a more finished appearance.

Attach dusty-plum yarn at the center of the back upper edge.

Make a short chain.

Before fastening it permanently, bring the chain over the opening and check it around your button.

It should slip over the button comfortably without being extremely loose.

Once you're happy with the length, secure the chain loop.

Sew the button onto the corresponding position on the front.

Test it several times.

The loop should open easily without pulling heavily on the crochet fabric.

Quick Fixes Before You Finish

The phone barely fits

Don't force it into the sleeve.

If the width is correct but the fabric simply feels stiff, check your tension. Link Crochet Tension for Beginners here.

The opening stretches too much

Add one neat round of single crochet around the opening.

My sides look uneven

Check whether corresponding rows were aligned before seaming. Stitch markers make this much easier.

The pocket leans to one side

Remove only the pocket stitches and reposition it. You don't need to remake the whole sleeve.

The button pulls the fabric

Your loop is probably too short. Give it slightly more length rather than stretching the crochet every time you open the case.

One Pattern, Different Phones

The useful part of this pattern isn't an exact number of chains.

It's the sizing method.

Measure the foundation against the width of the phone and the finished rectangle against roughly twice its height, while allowing for the device's thickness and the seam.

That means the same construction can be adapted to many phone sizes.

Current 2026 beginner patterns are also leaning heavily on adjustable sizing; for example, recent phone-pouch patterns specifically describe changing width and height to suit different smartphones.

Once you've made one successfully, try changing the pocket color or leaving the button off. You don't need to add more decoration—the contrast pocket already gives the project its own identity.
