I use them for the Little foot frame with my Simply Sixteen machine. I need 6” extra fabric for both top and bottom to wrap around the around the top bar. It’s hard for me to waste an extra 1/2 foot of expensive fabric when I can just baste a couple of strips along the top and bottom. By waste I mean it goes into my scraps where it may reappear sometime in the future for another project. Probably... well maybe... always hope. Basting goes quick.
