When stamping on washers…I am using the metal block, but where are you stamping? I am sitting on the (hard, cold) garage floor and using the step into our house as my “table.” It is NOT comfortable and my arm and neck are paying for it.
Of course, I am making LOTS and LOTS of items…so spending hours out there. BUT as hard as I have to hit to make the impression in the washers (usually 6-8 to make it deep enough.
I guess they are really hard compared to what you are buying?) but I am sure I could not do this in my house on my wood floors or ceramic tile…any ideas??
