I never liked the sandwiching part of making a quilt. Finally tried spray basting and it has made an incredible difference. It's quick and effective. I no longer crawl around on the floor, use hundreds of pins or have wrinkles/tucks when I FMQ. I no longer dread the sandwiching process and will never do it any other way. I admit to being afraid of it initially but WOW...what a difference it has made for me!
