I have checked on my quilt and the sandwich pieces are stuck to each other pretty good. I am impressed. I noticed one thing though, it is better to make thin lines with the glue rather than dots since the quilt is heavy and it will be handled more than a small piece. If you squeeze the bottle and move fast the glue comes out in a really fine line. I will start quilting tonight when kids are in bed and there is nobody that needs me LOL.
