I put a drop of resin in each of the small square shape molds and let it cure until it was almost solid. I put the screws into the molds and then covered them with more clear resin. Once the resin had completely cured I mixed some more resin but this time added a little bit of metallic brown pigment to give this lovely chocolate brown colour and then filled the molds to the top and left to cure under the lights. I was really pleased with the result and thought they'd make a fun pair of cufflinks!
