Went back and found your picture of the bargello quilt. You did a fabulous job on that top. I think you will need to check and see if when you get the backing and batting sandwiched to the top if you are going to be able to roll it and fit it through the throat on your machine. Would hate for you to get almost half way and discover it won't fit. May need to use a very thin batt. Although cotton seems to work best for me when machine quilting. Good luck, and post pictures when you have it completed
