Here is a super fun zipper pouch that everyone loves! This is easy to sew vinyl requiring no special tools.
This is NOT pre-quilted vinyl - YOU are quilting it. Please watch the video demonstration.
Here is the second one which was a live sesh.
For the quilted case version, the only hardware you need is a zipper. I did make KITS for you in 2 color ways, Deep Space is here and Pink Nebula is here.
There are 2 videos with a complete walkthrough.
