Just finished marking a Nerdlepoint canvas
Each Nerdlepoint canvas is a unique QRcode marked on a piece of 13-count Zweigart "orange stripe" mono canvas. (It doesn't really need all those adjectives, but I like describing the canvas as though it were a blued-steel submachine gun in a pompous 80s spy novel.)
Each canvas contains a unique QRcode. When you buy the pattern, you get a passcode that lets you redirect that QRcoded URL anywhere you like. The back-end platform is the same as the one I use for www.p8tch.com
I sold this particular canvas to Mary D. way back in *cough cough* SEPTEMBER, and am finally sending it to her. I'm so sorry for the long wait!
