collarmom

Hi All, Can someone help me? How was this done? I can't figure out how the impressions around the stamps stayed undyed. Thanks!

Good Morning All, I'm a leather newbie. I was looking for a nice leather collar for both my dogs and I amazed by the pricing (I know why now). I've attached pic of my first 3 collars. The one with the purple one with BIG bling is my 1st collar. My Second collar is the green one with the name plate My 3rd one is the one with the shotgun shells and My 4th one is the stamped collar. Just wondering what you all think. Thanks!!
