Well, your HO is good enough for me! For my printmaking, I have papers ranging from mulberry paper to mat board, so I should be able to find something on hand that works for me and my trusty Viking! I may try parchment paper, which I also have already, as I have heard some like that best.
Do you think the simple stars on the German site I posted would be an okay place to start? I could increase the difficulty and still have related blocks that way.
