Once I tried glue basting I've never gone back to anything else. It is so easy. Right now I'm quilting a large quilt that is very heavy. I can't imagine how heavy it would be if it were pinned. I'm not sure I could wrestle it through the throat of my machine if it had pins. With glue, no problem. My machine has quilted a lot of quilts with glue basting with no ill affects to the machine.
