You need your sunglasses on for this one. I used Alex Plus caulk and scraped it onto the cs with an old credit card. I wanted it to gradually slope from high ridges and texture on the outer edges to thin near the center but was only slightly successful with this. When it was dry i used a single edged razor blade to remove as much as possible from the center where i glued the image which i had colored with gel pens. Some of the grout came off in bits big enough to curl and re-apply for more texture. I also wanted to hide the straight edges of the image but there wasnt enough extra grout to work with. I applied a thin layer of the caulk to a small piece of acetate and when it was dry i scraped and peeled off enough to have lots to use for added texture. I didnt use any glue for this as the grout was rubbery enough to stick to itself so i placed the little bits then painted overall with gesso. When it was dry i played with coloring it; various paints, inks, and ended up liking the effects of markers better because my newest 3 markers have those almost florescent colors. I then topped it all with Pearl-X.
