I made one of these a while back and it worked great! but there was no room for any new thread :(. I kept saying I would make a new one but kept putting it off for other projects. You know what I mean don't you. Well here it is. It's much bigger now and I'll use my old bag for my vintage silk button hole threads (these are great for embroidery btw) You can get the pattern here on Craftsy
Anyway here are the pictures of my new bag!
Look closely, can you see that you do not need to take the spool out to get a length of thread. This is a super bag for hand applique projects!
