Sometimes it is good to throw out the rules
A girl that has quilted several years for 4-H used my frame and sewing machine set up to finish her quilt for the county fair. She showed up with "extra loft'" batting in a bag. I refrained from saying something as the she was on a deadline to get it done. It was a "scrappy" batiks that were very bright and busy. She used a very tight free motion "loop and swirl" I have to say the effect was really cool. I think with the fabric choice and the tight quilting the batting choice really worked. I have some batting like that tucked away, and am going to try it. You would not want to use it on just anything, but a bright, busy quilt, for a young girl, or a baby quilt, it would look great. I just thought I would share that with this group, in case you had those bags of batting, and did not know what to do with them.
