Thanks for your help, everyone.
I have bought about 70 stamps in the last two weeks, mostly on Ebay and Craigs list. About all of the stamps have been Craftool. I can see that Craftool is not the best stamp, but I have only been leather working for a couple weeks now so my designs are messed up more by me than a poor stamp. I will buy better tools in the future but the cheap ones get me started.
The knowledge you guys gave me will help me decide which tools are the better tools when searching odd sales.
Buying different stamps gets addicting, along with bidding on Ebay. I think I am enjoying buying the stamps more than doing the actual leather work. Is this normal? My wife says," no more stamps!" I say, "yes Dear", and think to myself, "where else can I look for stamps".
