There are several ways to baste a quilt sandwich, and I think I've tried them all. After pinning my first one, spread out on the floor, I knew I would never do that again - the knees were rather angry with me! So I found a big table (can put together two long ones) and tried pinning again. Just didn't like the way the fabric was "loose" when you took out the pins. Then I tried spray basting and thought I was in heaven....but oh so expensive and messy. Have just finished basting a quilt sandwich using washable glue (Elmer's school glue...washes out). I love the way the fabric is secure and won't pucker at all, as well as the glue is just downright cheap! I have started quilting and have found no issues. I will definitely be glue basting from now on. So you will have to try several different methods before you find the one that works the best for you. And this topic will give you just as many different opinions as the best type of thread to use! LOL. Your quilt is very pretty....be sure to give us another look when you have it done!
