Mike basicly constructed the base of these whilst i was at work.
He used the thick UVA foam playmats that you can buy in tesco and heat formed them in to a semi-circle and used the same UVA matting as the face to glue it to.
I added the faceplates when i got home and used pipe lagging cut in half to make the tyres. we painted the tyres in a PVA/acrylic mix.
the wheel faceplates are made from a mixture of Funfoam and UVA foam, i then used a dremmal to engrave the detail into the cookie wheels
