I wanted to see if I could emboss over an alcohol ink background created on Yupo. The answer is yes.
I had to keep my heat tool moving constantly, because the Yupo started to warp if I left the heat on any one spot for too long. The background was created with alcohol inks, with a gold mixative, and I added gold foil over the top, which stuck to the slightly sticky parts of the alcohol inks (I learned this trick from Jenny Colacicco.) I stamped the flowers from Wplus9 "Kind Soul" in Versamark, then embossed with gold embossing powder from Hero Arts. I fussy cut around the image, adhered it to a white card base, then stamped and gold embossed the sentiment from the same stamp set.
