I'm doing a king size quilt now using Marti Mitchell's Quilting in Sections technique which is similar to QAYG but uses larger sections. I've found it work well for quilting on a DSM for those of us who don't have enough experience to work with a large quilt on our regular machine.
I checked out having it quilted for me but it was going to be pricey and this is a quilt for our bed which means the 3 dogs will be on it all the time. I didn't feel that I wanted to pay a lot of money to have it quilted for me.
