I'm going to do a frame collage like this for the living room. Not sure yet if I want the frames to be all the same color or not. Some will have pictures in them and some will have personally crafted pictures/collages.
Jewelry is one of those things that can add up quickly. Contain your chains with a DIY necklace organizer made from a metal vent cover and vintage frame. For smaller pieces, try repurposing a cookie stand as display-worthy storage.
