The most mess I usually make is when I'm using my distress inks as I'm not one for 'messy crafting' but I couldn't resist trying this alcohol ink technique on acetate after i'd seen it in a magazine and as I'm going to a product workshop with the said inks next week I thought i'd better get in the mood.
I covered a piece of acetate with A I in shades of red then stamped on it with a scroll stamp and black archival ink then dabbed off the black and IT WORKED!! leaving a lovely background, I put a pale green card behind the acetate and the rest is history - see the picture, it took me a while to get the colours right as i felt it was far to red at first so had to 'grunge' it down a bit.
