I used a small canvas to practice on because I wasn't sure what was going to happen. 😒 I just did some scribbles, added torn pieces of paper, some color here and there, and then covered it with a thick coat of matte gel.
I actually forgot it was sitting upstairs to dry all last week because of holiday & family stuff! It's ok because you want to give it a day or two to completely dry. I then scratched some lines into it and added paint to get down in the lines, then wiped the rest off.
I really like the affect - easier than messing with wax!
I think I've got enough confidence to try a bigger piece now!
