I use homemade flour based spray, Elmer Washable School Glue or 505 spray to baste my quilts - there is not shifting going on then. I start in the bottom right hand corner and work my way to the left about a 9 inch swath, I continue doing this until I reach the center. I have done 120 x 120 quilts on my domestic and now my Baby lock Jane machines.
I got lost when ever I tried to start FMQ in the middle. I have taught my quilting g/f this method also and it certainly helped her with her FMQ.. Best of luck!
