How timely! I just got a box of vintage sheets today at an estate sale, and there were some that are too thin for me to use as fabric.
I was thinking of drawing on them with a sharpie and just trying to teach myself to paper piece or foundation piece. It would simply eliminate the paper part, right? And I like a heavier quilt since I live where it is COLD all the time! Since I have not learned to do it the right way yet, I might as well figure it out MY way. LOL!
