I was browsing through the tutorials on the Spectrum Noir blog for inspiration and found this by Linda Hill that looked like fun. Did you know you van stamp with your markers? I tried it and it turned out pretty cool. I used some mixed media style stamps by Crafters Companion that I wanted to ink up for a while now.
As you know the markers dry too quick to stamp after you color on the stamp, but if you fill a sprayer with clear alcohol you reactivate the ink (alcohol solves alcohol). I used some cleaning solution but you can use colorless blender or rubbing alcohol too. I also used it to clean up my stamps after that, I think that even if I didn't get it off it wouldn't stain unless you use some other solvent based ink but I got my stamps pretty clean using the cleaning solution. I wasn't brave enough to try it on clear stamps, I'm not sure if the alcohol and photopolymer will play nice but my rubber stamp didn't get hurt as far as I could see.
