Cathy sent me a link to a post about Karen O’Leary’s Map Cuts. They are hand cut, and Karen says this on her Etsy shop:
If you’re interested in a certain city, please send me an email and allow a few months for me to complete it. please note, each map takes quite a bit of time. Custom pieces will be hand-cut in the order that payment is received.
Just imagine doing this by hand! Amazing patience and dexterity.
