diy flattened spoon necklace - old spoons on flea market and flattened with a hammer. You need the right tools for cutting the handles and drilling the holes, or find yourself a handyman. Put a little silver heart, a small key & some beads.
DIY Spray Shells Silver spray all of those leftover shells with silver spray paint and you have an expensive looking decorative item. This would be awesome to do with gold spraypaint and include it in the centerpieces somehow!
