Don't forget ladies, 'tis the season for bargain glue! It's back to school time and Elmer's Washable School Glue is two for a dollar! Every time I go to WM, I pick up a couple more.
My only tip is not to use too much glue, which was how I did it at first, and I had lots of globby messes. Now I position my hand about 8-10" above the quilt and just slowly drizzle. Works pretty well! I don't have an outdoor space where I can spray the 505 although I do own a bottle of it. I'd rather use the nice, non-smelly glue.
