Turn sea shells into beautiful wall art! Gather all of those shells that you've collected on beach vacations and turn them into a pretty display. I'd start off by washing and boiling the shells first, allow them to cool, and then hot glue them together into something fun and whimsical like these dancing ladies on a wooden backdrop. This would look awesome hanging on the wall in just about any room! You could even add a splash of color with paint if you'd like.
