After I read this article I had to try it and am so glad I did as it works so great especially in my go to bag I keep in my purse . I am working on a GFG and use various colors of thread depending on what color hexi I am working on and instead of carrying spools of thread I use bobbins and this idea works so great. I went to a day quilt retreat yesterday and shared this with a other quilters and left a strip of binding spiral for them to try. No more pony tail holders for me, they are fine for spools of thread but I did not find them to work well on bobbins. Thanks for sharing a great link.
