I have been having great fun making tiles from fimo, sculpey and prosculpt clays, using an assortment of colours from the fimo,sculpey range and skin tone from prosculpt, all of these clays are great to work with, although it takes a while to condition the clay and your hands can become sore, but it is worthwhile,
Once the clay was rolled out to the thickness required I used a selection of rubber stamps to make the patterns in the clay, some have bits and pieces embedded in them, filigree's, beads etc, I then trimmed the clay to the size of tiles that I wanted, when a batch was ready they were coloured with pearl ex powders, placed on a baking tray and popped into the oven to cook, this is the first time that I have made polymer clay tiles but it will not be the last as I plan to make a mosaic picture's with them.
If you make the tiles thin enough they are great to use on atc's , chunky book pages etc !
