Basting spray is SO fast and EASY - it makes putting the sandwich together a breeze. No more wrinkles on the back. Just be sure to smooth the bottom layer carefully - and I would still tape it - but not too tightly. Then spray & place the batting. DON't spray the batting - it can melt! Finally, lightly spray part of the back of the top at a time and press it down. Gradually work your way across until you have it all spray basted. You're ready to sew. The whole thing shouldn't take more than 10 minutes!
