I actually had another piece to post for today, it was oil on YUPO again but I guess the oils take longer to dry on YUPO than on other surfaces & I couldn't scan it comfortably.
So continuing with my YUPO experimenting, I tried Genesis heat set oils on YUPO and came up with this little fellow:
1" x 1"
I didn't plan this one out much at all as I had no idea how the YUPO would react when baked, but it survived! I think I'm going to do more of this combo.
