I have recently begun using alcohol inks, and I have to admit that while I was intimidated by it at first, after using it, I LOVE IT!!! It works best on glossy paper or acetate (I just used transparency film). I used it on this card..
Happy For You ... both in the background (which was just on transparency film) and on the acetate flower (ghost shapes.. although you could just cut out your own shapes with transparencies as well). It is SO easy and SO much fun.
