I messed around with the stamps I made last night and discovered a few things.
1. You really do need to trim the stamp pretty close to the image, or get get the dreaded "flash".
2. Staz-on. stains the stamps slightly. But, the stamps aren't perfectly clear like some of the commercial ones you buy, so I'm not sure it's that big of a deal.
3. Like any other polymer stamp, prior to inking for the first time, the surface of these stamps also need conditioned-so the ink doesn't bead a top the image. Just a quick rub down with an eraser did the trick.
