I stretch out my batting on my tile floor in my breakfast room. And tape the sides with masking tape strips to stretch out wrinkles. Then I stretch out the backing on the batting. I fold it back in half and glue with elmers, starting in the center and glue about 12 inchs at a time across the quilt. I iron it to flatten glue globs, then I start gluing the other side starting in the center. Then I flip the entire thing and glue the front the same way but I am careful to square up the top as I go with the grids on the floortile. I also iron the front to flatten the glue globs. Then it's trim to the top leaving about 1" all around and just flipping it every now and then till it dries completely.
