I just finished a wheelchair sized lap quilt for my Mom. I taped the backing(flannel) down to my big table, then laid the top on, making sure it was smooth. Then starting from the middle, folded back one half of the quilt. Using Elmers glue drew thin lines is a back and forth "s" shape. Folded the half back down and patted it all together. Then did the other half. Let it dry overnight and grid quilted it the next day. Everything stayed together nicely. I haven't used it on any thing larger tho, and haven't tried using it if there is batting. I can't use the 505 spray (allergies, dang it), so the glue is the next best thing for me.
