I looked into it! It’s a matter of figuring out what size of stamp set I would need to go with what size of washer. Being a girl this really isn’t my area of expertise but I’ll figure it out lol. I do like how easy this is and to the common folk, they wouldn’t understand what this pertains to. I’ve also thought that stamping the numbers for the sequence of the seed phrase on the other side of the washer in case they got mixed up and for some reason the words weren’t memorized.

It’s on the to do list! Could really hide these suckers anywhere and make a few copies!
