  1. I cannot see any real difference between the two cuts,to me they look basically the same. I’ll keep trying.

    • The thing to look for is that nobody ever separates perforated stamps perfectly smoothly. Some of the perforations are going to have ragged or irregular tips. A die cut is always going to be perfect. So, take out your magnifier and if you say, “wow, every last one of these perforations is smooth,” you have a die cut, and if they’re not smooth, you don’t.
