Hi,
I use 505 all the time for putting my layers together......works the best of any spray adhesive I've tried. It also doesn't have the odor that some do, a few give me a headache within minutes.
I put my backing down on the table or floor, then the batting on top, fold the batting back halfway, spray it, unfold back on backing and smooth.....repeat with other side. Then I put the top on top of the batting and pull it halfway back, spray the batting, and so forth.
I was taught to always spray the batting instead of the fabric.
How does everyone else do it??
I love 505 spray....don't use pins or baste anymore at all. I also don't do as heavy a spray as some.....you have to find your own style with it.
