I saw this QR-3D project on Rockpool Candy's blog and wondered if a ribbon woven QR code would work. Firstly I created a QR code here (for this very blog!), and transferred the code to squared paper, so that I could follow the pattern easier. QR codes are made up a grid of 33 x 33. So I laid down 33 strips of white ribbon, and set to work weaving the black ribbon in.Finally finished! Interestingly the ribbon woven QR code doesn't scan, but a photo of it does. I wonder if this is because at a smaller resolution it hides the imperfections? I quite like the look at the underside - a QR code in negative.
