I made probably one of my more impressive knitting mistakes in all my time of knitting and I still couldn't tell you exactly what happened. The pattern was from Rowan and called "Lauryn Shawl" by Lisa Richardson. As you can see; mine didn't turn out as a shawl.
One of two things happened: either I totally blundered the count or I was shorted a skein (it was a kit).
Still, a very interesting pattern with a neat effect.
