I have just glue basted a poly batting...no problem with holding for me. After it dried, I did safety pin around outer edges to keep it from pulling apart...not sure if it would anyway...this is a 75 inch square quilt. The center is now quilted and have 3 3 inch borders yet to quilt and have been tossing the quilt from table to chair for the past couple of days as I mull over what stitches to use on the borders. Nothing's come apart. Good luck....I love glue basting...
