Most of us wore old high school and college formals. Mine was an old bridesmaid dress. I couldn't find a necklace I liked to go with my dress, though, (and I didn't want to look like a 29 year old trying to look like a 16 year old, so I eschewed my old rhinestones and "formal" necklaces). So, I made one.
I wanted to make a necklace using those lucite flowers I've been seeing a lot on Etsy these days, but didn't have the forethought to order any online ahead of time (and they're not available in local stores). So, I made my own flower bead with Sculpy and made my own necklace.
