Here's my sketch: (math major, not art major!)
And here's the back:
The back of Dad's vest.
It's so exciting to see it halfway done. It has been a struggle to find good times to knit a heavy wool vest here in Florida. Not the ideal playground knit.
The two side cables are borrowed from Linda Romens' Faux Cable Pullover in "Knitting in America". The rest is my design. Let me tell you it took forever to work out all the ribbing so it would meetup with the cables. I goofed on the center cable, but I don't think you can see it in the picture. Yarn is Knitpicks...which I love. Still needs blocking, but I'll get to that once the front is done.
