A Sockmatician Tutorial - "Strantarsia"

"Strantarsia is the name I have given to the technique of placing an intricate, stranded design panel to a section of knitting in the round.
I use this technique in my iSqr pattern, which is a case for an iPad, knitted in the round, featuring a stranded QR code on the front, which is scannable, and can point to a URL of your choice. Search "iSqr" on www.ravelry.com
