It's so funny to read this - the same thing just happened to me last night! I was thinking about a technique I did for some cards a few years ago. I knew I squirted alcohol inks on something, used it as a stamp pad, and stamped on both glossy and regular cardstock.
Later today, it finally dawned on me that it was baby wipes!!! Well, I was so happy I figured that out, but ... when I sat down to do it, I selected a photopolymer stamp. Ugh. It is stained beyond belief! It still stamps well, but good grief . . . it's been a long time since I've used alcohol inks, but how could I have forgotten that?!?
