I use thumbtacks to align. Place the tacks thru the back in the places you want to align. Put a piece of painter's tape over the heads. Place the backing on your pinning surface & secure. CAREFULLY lay the batting on the backing without sticking yourself ;-). Now you can lay the top on, using the tacks to align. Again, be very careful. Pin securely, then remove the tacks.
