I love the rather masculine cogs and wheels and weird "inventions" some artisans have been selling on the likes of ebay and Etsy, but decided on a more feminine style.
I've altered some wooden hearts using various coloured embossing powders and UTEE and decorated them with tiny cogs and wheels, brass and copper findings, etc. I've arranged the pieces on brass and copper chain and added antique-style keys and other findings to compliment the mini fob watches I bought in specifically for this project.
