I often comb thrift stores, garage sales and flea markets looking for items to include in my mosaics. I started making these mirrors with the a lot of costume jewelry found at a flea market and some lots off of eBay. They are my newest obession.
This mosaic was done on the infamous IKEA 10" mirror using mastic which I colored with black concrete colorant. The jewelry pieces (earrings, watches, pendants, pins, necklaces and chains), all predominantly silver, were embedded directly into the mastic, leaving no need for grouting. Grouting this type of mosaic can be messy messy messy, due to the nooks and crannies of the jewelry.
