Crochet Sunglasses Case Tutorial

Make a practical handmade home for your favorite sunglasses with this simple crochet sunglasses case. The design uses a straightforward rectangular body, a protective flap, and a button closure, making it a relaxing project for beginners and an easy handmade gift idea.

Skill level Beginner
Hook 4 mm crochet hook
Construction One-piece case + flap

Before You Begin

This crochet sunglasses case is designed around one simple idea: create a snug rectangular pouch that protects the lenses and keeps the sunglasses easy to carry.

Instead of relying on one fixed stitch count for every pair of glasses, the case is made to your sunglasses. That means you can adjust the starting chain and the number of rows according to the size and shape of the glasses you want to protect.

The finished project has a simple front and back body, a folded bottom, side seams, and a flap that closes over the top with a button. Once you understand the basic construction, you can easily make several versions in different colors.

Important: Measure your sunglasses before choosing the starting chain. The case should be slightly wider than the glasses without being so loose that the glasses slide around inside.

Materials & Preparation

What You'll Need

  • Worsted or medium-weight cotton yarn
  • 4 mm crochet hook
  • Yarn needle
  • Scissors
  • One button for the closure
  • Your sunglasses for measuring

Why Cotton Yarn?

Cotton is a particularly useful choice for a sunglasses case because it creates a structured fabric that does not stretch as much as many soft acrylic yarns. It also gives the finished case a clean handmade texture.

You can use another yarn if you prefer. Just remember that changing yarn weight or hook size will change the finished dimensions, so measure the case against your sunglasses as you work.

Choosing Your Button

A medium-sized wooden, resin, or decorative button works beautifully with this design. Choose a button that is easy to grip and large enough to stay securely attached to the crochet fabric.

Gauge, Fit & Finished Size

A sunglasses case does not need a strict gauge measurement because the project is designed around the item you want to store inside it. However, keeping your stitches reasonably even will make the case look neater and help it hold its shape.

Measure Before Crocheting

  1. Measure the widest part of your sunglasses.
  2. Add a small amount of ease so the glasses can slide inside easily.
  3. Measure from the bottom edge of the glasses to the highest point.
  4. Allow extra length for the flap.
Fit checkpoint: Your foundation should be wide enough for the glasses to enter without forcing them, but not so wide that the case becomes floppy.

If you want a more structured case, use tighter tension or a slightly smaller hook. If your fabric feels stiff and difficult to work, loosen your tension or try a slightly larger hook.

US Crochet Abbreviations

  • ch — chain
  • sc — single crochet
  • sl st — slip stitch
  • st — stitch
  • rep — repeat

The main body of this project uses simple single crochet, making it a good practice piece if you are still becoming comfortable with basic crochet stitches.

1

Measure Your Sunglasses

Place your sunglasses flat on a table and measure the widest horizontal section. This measurement determines how wide your crochet foundation needs to be.

Next, measure the vertical height of the sunglasses when folded. Remember that the finished case needs enough depth to cover the entire pair.

Checkpoint: Write down your width and height measurements before you begin. This makes it much easier to check your crochet as you work.
2

Create the Foundation Chain

With your 4 mm crochet hook and cotton yarn, make a foundation chain that corresponds to the desired width of your sunglasses case.

Place the chain beside your folded sunglasses. The chain should span slightly wider than the glasses.

Do not make the foundation extremely tight. A tight starting chain can pull the bottom edge inward and make the finished case narrower than expected.

Foundation: Chain until the piece is slightly wider than your folded sunglasses.
Size checkpoint: Compare the foundation directly with your sunglasses before crocheting the first full row. Adjust the chain now if necessary.
3

Work the Main Body

Begin working single crochet stitches across the foundation chain. Continue in rows, turning at the end of each row.

Row 1: Single crochet across the foundation chain. Row 2 onward: Chain 1, turn. Single crochet across. Repeat until the crocheted fabric is long enough to wrap around the sunglasses and form the case.

Keep your edges as straight as possible. Count your stitches from time to time, especially during your first few rows, because accidentally adding or losing stitches can cause the case to become wider or narrower.

Keep the Fabric Even

Insert your hook into the correct stitch at the beginning and end of every row. The first and final stitches are easy to miss when working single crochet, so slow down around the edges.

Checkpoint: Fold the growing rectangle around your sunglasses. You should have enough fabric to cover the front and back while leaving enough length for the flap.
4

Check the Case Depth

Before closing the bottom, place the sunglasses on top of your crochet fabric and fold the lower portion upward.

The folded section should create enough room for the glasses without squeezing the sides. If the case is too short, continue crocheting more rows.

It is much easier to correct the size now than after the seams and button have been added.

Beginner tip: Check the fit several times while crocheting. Handmade projects do not need to follow a fixed measurement if the final fit is comfortable and practical.
5

Form the Bottom Seam

Fold the lower part of the crocheted rectangle upward to create the pocket that will hold the sunglasses.

Align both side edges carefully. The more accurately you align them, the cleaner the finished pouch will look.

Using your yarn needle and matching yarn, sew the bottom and side edges securely.

Seaming Options

You can use a simple whip stitch for a soft handmade seam, or a mattress style seam if you want a more concealed finish. Keep the stitches secure but avoid pulling so tightly that the edges pucker.

Seam checkpoint: Insert the sunglasses into the pouch before finishing the seam completely. Make sure the case is wide enough and the glasses sit comfortably inside.
6

Create the Flap

The remaining upper section becomes the protective flap. Continue crocheting rows until the flap is long enough to fold comfortably over the opening.

Keep the flap aligned with the body of the case. If your edges begin leaning to one side, check that you are working into the final stitch of every row.

Flap: Continue working single crochet rows over the remaining upper section until the flap reaches the desired length.

Shaping the End

The flap can remain rectangular for a simple modern look. You can also slightly round the corners by working decreases near the final rows. For a first attempt, keeping the flap simple makes the construction easier.

7

Add the Button Closure

Fold the flap over the front of the case and decide where you want the button to sit.

Mark the position with a stitch marker or a small piece of contrasting yarn.

Sew the button firmly onto the front of the case. Pass the yarn through the button holes several times and secure the yarn on the inside.

Create the Closure Loop

Make a small chain loop from the center or edge of the flap. The loop should fit comfortably over the button without stretching the crochet fabric.

Closure checkpoint: The button should hold the flap closed without making the fabric curl, stretch, or pull excessively.
8

Weave in the Ends

Once the case is assembled, use your yarn needle to weave every loose yarn tail securely into the inside of the fabric.

Work the needle through several stitches in different directions before trimming the excess yarn.

Avoid leaving long loose ends inside the case because they can catch on the sunglasses when they are inserted or removed.

Troubleshooting

My case is too narrow

Your foundation chain may be too short or your tension may be tighter than expected. Add width by restarting with a longer foundation chain.

My case is too loose

If the sunglasses move around too much inside the pouch, reduce the foundation width slightly or use firmer tension.

The sides are not straight

Check your stitch count at the end of every row. Missing the final stitch is one of the most common causes of tapered crochet rectangles.

The flap does not line up

Lay the case flat and compare both edges. If one side is longer, check whether stitches were accidentally added or skipped during the body or flap rows.

The fabric feels too floppy

Try a firmer cotton yarn, slightly smaller hook, or tighter tension. You can also add a simple fabric lining if you want additional structure.

Finishing & Final Checks

Before calling your sunglasses case finished, place your folded sunglasses inside and close the flap.

  • Check that the glasses slide in without force.
  • Make sure the lenses are fully covered.
  • Check that the button closure stays secure.
  • Look over both side seams for gaps.
  • Trim any remaining yarn tails.

Optional Blocking

If your case looks slightly uneven, gently shape it while damp and allow it to dry flat. Do not stretch it aggressively because you want the finished pouch to maintain its protective shape.

Remember: Crochet fabric can protect sunglasses from scratches and everyday contact, but it is not a hard protective case. For expensive or fragile sunglasses, use the crochet pouch inside a rigid case or another protective container.

Variations & Personalization

Try Different Colors

Make the body in a neutral cream, beige, brown, or gray for a classic accessory. Bright colors are perfect for summer projects, while darker shades create a more understated look.

Add Stripes

Change colors every few rows to create horizontal stripes. This is an easy way to make the same pattern look completely different.

Use a Decorative Button

A wooden button gives the case a natural handmade appearance, while a colorful resin button can turn the closure into a statement detail.

Add a Small Flower

Attach a tiny crochet flower to the front flap for a feminine, playful variation. Keep the decoration small so it does not interfere with the sunglasses.

Make It a Gift Set

Crochet a matching pouch for sunglasses, a small coin purse, or another accessory using the same yarn colors. Together they make a thoughtful handmade gift set.

Care & Storage

Cotton crochet accessories are easy to maintain, but always check the care instructions for the specific yarn you used.

  • Keep the case away from excessive moisture.
  • Clean gently rather than scrubbing the fabric.
  • Allow it to dry completely before storing sunglasses inside.
  • Store the case flat when it is not being used.
  • Check the button and closure loop occasionally for wear.

If the case becomes misshapen, gently reshape it and allow it to dry flat rather than pulling aggressively on the stitches.

Why This Makes a Great Beginner Project

This sunglasses case is small enough to finish without committing to a large project, but it still teaches several useful crochet skills.

  • Working consistent single crochet rows
  • Keeping straight edges
  • Measuring a project for a real object
  • Creating a simple folded construction
  • Joining crochet pieces with a yarn needle
  • Adding buttons and simple closures
  • Customizing size and color

Once you understand this construction, you can use the same basic idea to create cases for phones, reading glasses, crochet hooks, small notebooks, or other everyday items.

Happy Crocheting! 🧶
