Hello, mers.

For the tail I am making, I was originally going to just cover a bra primarily with matching neoprene and decorate it, however, I did fall on a very nice deal for large shells, so I decided I would also attach those. Wondering, though, because attempting to drill holes in them makes me VERY nervous - would hot gluing them to the bra likely hold them on? The bra has lace on it, so there is pretty good texture for the glue to hold on. Has anyone ever tried this? Opinions on the idea? Etc?
