As my clay atc's were so successful, I decided to make some 4 x 4's and added the clay pieces as the focal point. I created the backgrounds in exactly the same way as the others. Top left is mounted on a piece of mica. Top right is a mould whereas the other three pieces have been stamped into, so it's raised. On the bottom two I've added wire mesh, wire and gems.
*****Edited***** The sun is shining this morning so I've been able to get a better photo to show the real colours.
