Hi Jan, I'm not the best person to give you advice, because I haven't actually done it yet, but I have been collecting information about the QAYG process because that's what I want to do. I think I found the Forum site where it was discussed though:
viewtopic.php?f=14&t=3819 -- the Forum topic is Free Motion Quilts Squares as you Go, and it's under Help Me Learn to Quilt > Hand & Machine Quilting. Several people made suggestions of web sites to check out, including me -- I listed all the sites I have found helpful. Please let us know what works for you! I plan on doing the Hugs & Kisses quilts (one for each granddaughter) by QAYG methods.
