I am inspired. I have had a mid-arm for almost two years and haven't touched it, except to move it and run into it. I have been "afraid" to try it, partially because I didn't want to ruin a top I made and partially because I am too attached to my stash to start pulling fabric and playing. So, I am going to go purchase two twin sheets, some cheap batting, and give it a whirl. I figure I can always use the end result as a picnic blanket or something.
I lived with a rancher's wife (as their cook) during my last year of college and she used to dye white sheets to match her quilts. She always used sheets as backing, but she was very frugal and I always saw it as "hillbillish". Now I know better!
