Mindless, I wish I had a dollar for every item I bought with good intentions and then didn't use for a long time! A year shouldn't make much difference with that glue. I would think you were right about the glue dissolving in the dye bath, but they do have pictures of the finished fabric. Maybe it's a matter of the fabric taking up the dye quickly. Presumably the glue, if it's completely dry to begin with, would take longer to dissolve. My only experience with dye was a t-shirt tie-dye kit from Joann's that I did with a grandson a couple of year ago, and don't remember much except that it seemed to work quickly. He wore the t-shirt several times and it didn't fade. I think with this I'd use it in a wall-hanging to avoid a lot of washing. I also experimented with a tie-and-bleach technique on an old dark t-shirt, and that's another option that might work well with the glue. It's less fun than adding colors.
