I've used the upper one many times on a
babylock, and it works great. I think if you don't want to stablize the fabric....Starch the heck out of your fabric first, that just might stablize it enough. FYI, after making a few of these squares and please try a number of your decrative stitches...way fun, now cut the blocks into smaller squares and include them in your next quilt project. Your gonna love it! Enjoy!
