How to mount Tillandsias: "You can use glue, wire, fishing line, twisty ties, nails or staples. We use E6000 glue as it is waterproof and dries clear, but you can use any kind of glue you like (except SUPERGLUE); a plumbers glue is generally better because it is waterproof and doesn't break down. Hot glue and liquid nails tend to give way after a while because of constantly getting wet. Goop, Shoe Goo and Tilly Tacker are completely waterproof, and will not let go."
