I have been procrastinating about assembling my finished quilt tops as I am fairly new to quilting still. I have 4 finished tops here that are about queen sized. A couple of weeks ago I used 505 for the first time on a crib quilt and was so impressed how easy it was. Sure beats the "old way" of pinning. Well today my mom said she would help me. So I got my first quilt sandwiched and used 505 to adhere the top. I then realized it would be easier to flip it over to adhere the backing after she arrived because of its size. An hour and a half later we got into it, flipped it and adhered the back. All went together smoothly. Even mom was impressed with the 505 and couldn't believe how much easier it was from when we have pinned. On to quilt 2. Tried the 505. What a disaster. Too many puckers we couldn't get smoothed out for the life of us. Decided to put it aside as I didn't know what to do at that point. On to quilt 3 and 4. Decided we were so disgruntled at how that last quilt went together that we pinned them. They came out sandwiched beautifully. Here is my dilemma- What do I do with my fumbled top? I can't FMQ it this way because it will pucker. I don't really want to wash it to get the adhesive out because I don't want the raw edges to fray. The only thing I can think of is peeling apart the layers, washing backing and top on gentle to remove 505 adhesive and hang on the line to dry so they won't fray on edges and start over with pinning together and throw batting away and start with new. I also can't figure out why it was such a disaster. They only difference I can think of between the first that went so well and the second was I gave a hour and a half for the top to dry and adhere before flipping. With the disaster one we did one side then instantly flipped to the back. I don't know if that could have affected it or not. Thoughts? What would you do to salvage the quilt top. I have too much time invested in piecing to screw it up on the last steps. I know I won't be happy unless I can correct it and get the puckers out. Thanks for your ideas.
