This is a test sample. Yes that sounds good.
I saw a cute one on Pinterest and tried to copy it without looking at the pattern.
I took 2 pieces of scrap material, sewed it together, cut off the extra length. I sewed the sides together with the elastic, but had to unpick that. The case was a bit too wide to hold the ear buds securely.
So I used the top I cut off and used that as a bag for the ear buds. I sewed the elastic to the outside stretching it a bit this time, but probably should have been on the inside of the ear bud bag. Yes I purposely used the inside fabric for the ear bud bag.
Still very usable. Just need to work on the next version...
