I started using zippers several years ago. I've also purchased a blind hem stitch machine to put the zippers on the quilts. It saves me SO MUCH TIME! I have a Gammill with the Statler. While I'm quilting one, I can be sewing zippers onto several others, cutting out the time it takes to pin/unpin between quilts. With the blind hemstitch I just pull a string and the zipper comes off in seconds. However, I usually wait to remove zippers until I've inspected the back thoroughly. If I have a problem, run out of thread or just need to take the quilt off for any reason, I just zip it back on when I'm ready and it goes back to where is was.
