I've found that the best way to align them is to mark both the metal and the stamp. On the metal I drew concentric circles with a cross hair. On the stamps I marked the top center and bottom center. It's easy to get stamps rolled in the wrong direction so I find it a lot easier to do it this way.
Here's are some photographs of the progression -
This is the log I've set up to stamp on. I was so lucky to gt this one. I'd been looking for one but had wanted it to be only about a foot tall and really wide. One day when we were cruising down by the River Arts District in Asheville we ran into a county tree service cutting down some trees in one of the lots. They were simply huge - and just what I was looking for. The guys were so very nice and not only helped me and hubby pick one out but one young hunky guy carried it to the car for us. SCORE! I tried to get him to accept a tip so he and the guys could get a pop or something but he refused. What a nice young man. Nice people are just EVERYWHERE!
That's all for now. I will try and be more consistent with posting....honest!
