I am no expert in adhesive issues... but I have found that hot glue works best for me with tacking fabrics or items like twigs, twine, little foam items, etc. Even then, you can pull it back apart. In the past, I had repairs done to many of my blowmolds using hot glue and all of them are popping apart. The hot glue will not hold plastic together, especially in cold weather. So I only use hot glue for the 'lightweight' type of crafts now.
