I did a twin size quilt last week with glue.
Lay the batt down on some surface. I used my queen bed.
Smooth the back down on top of it. Lift up about half of the back fabric, drizzle glue all over the batt (you don't need a large thread, just a thin line). The lines can be up to 6 inches apart, or just put down spots. Fold the back down again and smooth very well. Now work on the other side. Fold back, drizzle glue, smooth down. You can let this sit until dry, or use a hot iron and just press down on a lot of spots to dry the glue a little faster.
When the back is dry, turn it over and do the same thing to the front. Smooth it on, fold back, drizzle glue, smooth back in place. Then do the other side. Let dry or use the hot iron.
After this was done, I picked up my quilt as if it were one piece of fabric, took it to the sewing machine and did FMQ. It never moved.
This is so much fun. I hope you try it.
