I have put my zippered leaders to the test this week. I taught on leaders last week in my longarm class and showed my zippered leaders. This week I loaded the next quilt on the spare leaders while mickey was working the quilt on the frame. I love it! What a time saver to zip off a completed quilt and zip on the next quilt in the queue. I was able to do two quilts a day using this technique and catch up on edge to edge quilts. Next week it is back to custom quilts but I will be using the zippers now all the time. It was well worth all the time spent making them.
