DIY Tutorial: Iridescent Flex Frame Sunglass Case

May 2, 2018


Sun’s out, time to get your dose of Vitamin D! Honestly it’s mostly sunny all year round in Singapore where we’re based in so I’m used to always carrying a pair of sunglasses in my bag all the time. I do own quite a number of pairs, and after years of carrying them around realised that I do like the flex frame cases the best! They are light, give my sunnies ample protection from scratches in my bag, and it’s super compact when empty. I can’t believe I used to bring around those chunky hard shell cases!

Many PU leather type materials also have a felt/furry layer attached to the back and that makes a pretty good lining for the case. If you’re using regular fabric, you might want to double up with another softer layer inside just to give it some structure and cushioning! The PU was also great for this project as I didn’t have to worry about the hems! This material doesn’t fray and so just cutting it exactly to size worked well.

Using the free downloadable template as a guide, cut out two pieces of the chosen fabric according to size. You may want to adjust it longer or wider based on the sunglasses that you wish to house.


Working with the wrong side of the fabric facing up, fold down the top flap according to the thickness of the flex frame you’re using. In our case, it is 1.5cm.


Using a sewing machine or just by hand, sew down the flaps to create a strip that will be the casing for the flex frame later. Repeat to the other side.


Facing the two right sides together, sew down along the sides of the two pieces, reinforcing the start and the end where the opening of the case is.


Flip the case inside out such that the iridescent fabric is facing the right way. It was a bit tricky to flip this fabric as it was really stiff, but a softer PU or fabric will be fine. 


Insert the flex frame into the strips, one on each side, and secure with the pin hardware.


Done! Squeeze, and put in your sunnies and you’re ready for an adventure!



If you can’t find the same diamond stud iridescent fabric I used, you could also opt to use other cool fabrics such as this Purple Holographic Leather or this Mirrored Holographic Fabric. Alternatively, you could also choose to work with leather, or just regular fabric, just ensure that you check that the back of the material you use isn’t too rough or it might scratch your sunglasses!
