Step 1: Materials
*Wet and Dry. From the sandpapers section in the hardware. A range of grits going up to the finest available (the higher the finer). I've 400, 800 and 1200.
*Renaissance Wax. You can pick this up on ebay. Mine came from the UK and was about $20 (including shipping for the 65 mls but this is heaps (for me).
*A cloth to clean off your polymer clay pieces with. I use old torn up sheets.
*Newspaper for the table.
*A dish of water with a tiny bit of dishwashing liquid (a drop). It helps to keep things slick.
*A cloth to apply your wax. I use a bit if flannelette.
