I use to baste using a three rail quilt frame. What a chore. If you machine quilt then use Elmer's School Glue diluted with water to spray the batting, smooth out the top on the batting, press dry and then turn and repeat with the baking. I can baste a queen size quilt is less then 30 min. using fold out tables. My quilt sandwich is completely smooth and flat, no way a wrinkle or pucker can happen. The glue washes completely out. Elmer's is a thick starch product not a chemical glue product. Elmer's knows kids will ingest it so it is non toxic. I gave my quilt frame away.
