Ah! So cool! Just grab a roll of tp, some joint compound, and and some kitchen supplies and prepare yourself for one fun (and messy) afternoon of creating! I love the idea of using them as a centerpiece or mixing in some fun beach finds and clustering them together as living room decor! Heck, they would even look awesome all stuck together and hung on a wall! OoOo! Fun! What do you think? What would you use paper barnacles for?
