I also did a Qr code for my grandson for his high school graduation this year. Instead of piecing a large Qr code that I had seen on this board. I did 9 Qr codes enlarged them to 8 inches square and printed them on fabric then framed each code and assembled the quilt. DGS was very surprised his grandmother knew about the QR code and he had 9 secret messages form his Grandmother!!! It had the WOW factor when he opened it!!!
