I forgot to mention in my previous response. To get the perfect circle, I place freezer paper in my printer, draw a circle from "shapes" in word and make several sizes, then print. I cut the chosen circle out, fuse it down to my fabric, cut 1/4 inch around the freezer paper circle. I'm not good at drawing or even tracing perfect circles, so this works for me. I am good at the quarter inch...been quilting too long, I guess. Ha! Some people use glasses, jar lids, compasses etc. ( still don't get those straight) You can use the freezer paper circle numerous times, just peel and press on the next fabric piece. Someone told me in class that they make a two pencil little holder that when you put the pencils together in it, you can trace around anything and it automatically marks a 1/4 inch. That would be handy. Another lady at the guild said she just tapes two pencils together. I guess that work too.
