I shouldn't sell them. I have lots and lots of them. Most have never been used. More of a collection or must have at the time.
I started slow by selling my 4 x 4 dies at first I couldn't bare parting with them and then suddenly I couldn't stand not seeing them get used. I have not missed them but then after collecting years of 2 x 2 and most of the retired I worry that I might be sorry.
Tell me your experiences if you sold or saved them.
