Freeze - who not make up a sandwich of some extra fabric - either leftover from something else or some "what was I thinking when I bought this?" fabric and some batting. Pin-baste it and use it as a practice piece to learn free-motion quilting. Like everything else, it takes doing something over & over to master a skill. I am not nearly as good as I would like to be, but I don't let it bother me - I just keep on "practicing." I took several machine quilting classes. I learned something (lots of somethings) each time. In 2 of the workshops, we needed to make this sandwich using 1 yard of 2 fabrics & batting. We were to divide this sandwich up into 4 rows of 4 squares each. We were to use SILK thread - love that silk! - In each square we were shown a different filler pattern and were to fill the square with that one. It's amazing how much better I was after just that 1 class. Try it a few times - you just might start to get the hang of it. Who knows.
