Glasses Pouch with Flex Frame

I’m the kind of person who always remembers to bring her old 3D glasses to the cinema, but still gets surprised every time when I put them on and they are in a pitiful state. It shouldn’t come as such a big surprise, since I just throw them inside my bag without any kind of protection – something I’d never do with my seeing glasses. Not very clever, I know…

So, since I have tons of leftover fabric and some quilting filling, I decided to make my own cases. I’ve chosen the flex opening because I find it very easy and discreet – well, and because I’d never installed a flex frame before and who can say no to a new craft?!

Classes Case with Flex Frame

You’ll need:

  • Fabric in two different colours/prints (one for the outside and another for the inside of the case).
  • Interfacing/quilt filling (optional, for extra protection).
  • Thread that matches the outside fabric.
  • A flex frame and some pliers to mount it.


1. First you’ll have to create a pattern adapted to the final size you want.

On top, there should be a straight section that will become the opening for the flex frame.

  • Its width should be the length of the flex frame + 2 cm + seam allowance. For example, I had 7cm-long flex frames, so I measured 11 cm (7 + 2 + 2 cm).
  • Its length should be 2x the width of the flex frame + 1cm wiggle room + seam allowance. I measured around 7 cm.

The rest of the body should be as long as the glasses or whichever object you want to keep inside the pouch. You can make the shape straight all the way down for a flat case, or slightly larger at the bottom for holding bigger objects.

2. Cut the pattern twice from the exterior fabric, the lining fabric and the interfacing.

3. Attach the interfacing to the outside fabric, and sew all around both shapes as close to the edge as you can.

4. Pin both sides of the outside fabric right sides together and sew along the edge, leaving open the top part where the flex frame will go (7 cm long in my case). Repeat for the lining fabric.



5. If you’re making a flat pouch, you can skip this step. If you want to make a wide, flat bottom, you’ll need to “square” the corners:

Cut a square in the bottom corners of both the outside and inside shapes you just sewed together.

Open one the corners and flatten it again on the opposite sense to get a flat seam on top (the side seam line should be matched with the bottom seam line). Sew along the edge and repeat on the other side, then on the other fabric.

6. Trim away the excess fabric on both pieces.

7. Now you’ll have to attach the top parts of the exterior and interior fabric together. Match up the top of the exterior fabric with the top of the lining fabric, right sides together (this might sound a bit confusing, but the pic below should help).

Top Flaps

8. Sew one of the sides all around the edge, stopping when you get to the part that you sewed before. Then sew the other side, leave the top open so you can turn the pouch right side out later.

9. Once again, trim away the excess fabric.

10. Turn the case right side out by pushing the fabric through the gap you left earlier.

Turning Right Side Out

11. Pin the opening you left and sew as close to the edge as you can to close it. It doesn’t matter if it’s not perfect, since it will be on the inside of the case.

12. Now you’ll have to create the actual opening for the flex frame. Fold the top flaps half down towards the inside and sew as close to the edge as you can. Using thread in a colour that matches the fabric will give much nicer results.

Sewn Frame Opening

13. If your flex frame doesn’t have one of the sides already mounted, insert a pin and secure it with pliers. Then take the flex frame and gently push it into both openings at the same time. (This is why you needed some wiggle room when measuring the opening! Otherwise it will snag and rip the fabric.)

Pushing the Frame In

14. Once the frame is through the other side, insert a second pin and secure it with pliers. You’re done!
