This is an ATC I made last night. I've called it toxic waste because that's what I thought it looked like when I finished it. I've used a mountboard base, cut holes in it and put copper mesh behind. I created the background using lots of textured bits and pieces which I stuck on using PVA glue and heat dried. Then I painted over it with copper acrylic and added metallic rub-ons over the top in various colours. The skull is Grungeboard which I've painted with acrylic and added copper metallic rub-on over the top.
