Lovely! I have a friend who has made a number of those types of things. I try to not have too many works in progress at the same time, and I kit out things into project boxes, but it is nice to have suitable project bags for portable projects instead of reusing grocery bags. I'm especially finding that now as my Tuesday group meets outside instead of inside
I do have a number of the clear zippered cases that sheet sets or blankets sometimes come in that I picked up at the thrift store. They come in all sizes from pillow case to king comforter.
