Your quilt is lovely.If I have a quilt I am particularly worried about shifting, I baste it with water soluble thread. The one from Superior Threads is great in both bobbin and top. Sometimes I just out big wavy lines across the entire quilt, 6 - 8" across, sometimes I do an almost stitch in the ditch on the blocks ("almost" because I don't worry about a little wiggle since it will all wash out anyway). Then I take out all the pins, if I have used them, since the sandwich is nicely put together. I am going to do my first Baptist fan quilting on a lap quilt I made ages ago. I just got it spray basted and stabilized with water soluble thread. I hadn't thought of the fact I would be quilting bias lines, so I am glad I did it!Pam
