For both of my ATC's I used stamps by Stampsmith. I stamped with brown Staz-On on to glossy cardstock. Glossy cardstock and Staz-On seem to produce the best results for me. The Staz-On dries instantly which I like. I have found when using these photo stamps it helps to stamp onto a mouse pad or soft surface. Also it's important not to use too much ink. If you are stamping multiple images, clean your stamp in between because the stamps gets rather gunked up. I have found sometimes I stamp my first impression on scrap paper and use the second impression so as not to get too much ink on my paper. Seems it takes me more tries to get a good impression with these types of stamps, but I like the results and look of them when I am successful.
