This tag is a bit of a combination of a technique that France showed us over on day #1 of the PA blog using crunchy wax paper and a brayer and the recipe over at Dragons Dream TIO blog of a light bulb, yellow and wire.
I used haystack fresco paints for the background, I used mustard stazon to stamp the TH cog images. Various yellows (zesty zing, pumpkin soup) were used on the crunchy wax paper, the TH light bulb was stamped in timber brown stazon onto acetate and painted from the back with haystack fresco paint. This was mounted onto 3d foam and attached to the tag. The wire has been bent into shape and placed over the top of the stamped image.
