|Transfer using hot iron on OZ Kut|
If somehow you don't know, OZ Kut is the current reincarnation of the long passed PZ Kut, on offer from a fellow letterboxer at the US-based Stampeaz. Not affiliated with her or Stampeaz in any way, but I'm not aware of any other places dedicated to stamp-making like her shop is and she is lovely to order from, with excellent service (given all my quirky asks to try to get the carving material to Canada as cheaply as possible).
The cost for the material is relatively inexpensive - before shipping, of course. For anyone reading from the US of A - you are very lucky and privileged to have such an inexpensive postal system. And no risk of customs/duties at the border. Sigh. You are truly living the dream.
Anyway, there is massive benefit in having a fellow letterboxer be involved in the carving material creation process, this stuff is all-around great...
