I had made a "thread catcher" for my travel hexagon bag. I had to make it smaller than the original I had seen, so it wouldn't take up too much room in my bag. This is a picture of my travel hexi bag with a little hexagon pin cushion attached with a snap. My sewing kit is in the front (made from an Altoid tin), and the mini-thread catcher I made is on the right.
At my last retreat, I showed it to Lora, and she wanted to make one. She gathered enough materials for everyone at the retreat, so almost everyone decided made one. We made the "normal" size. If you are interested in making one, I found the "pattern" on a YouTube video here.
These are the thread catchers we made at the retreat. I think they are quite colorful!
