How do you measure?

How do you measure 3 soccer games, a fiddle rehearsal and knit night??

8inches on the back of the Eros Drifters Shell!
The front of the shell was finished at a different soccer game on Mother's Day. I have to say that I love the colors and how this works up. Sometimes it feels like I knit and knit and knit and get nowhere because it really is like knitting with string, but the end product is very pretty. This will need to be worn with a tank top or camisole underneath as it is quite see through. Hopefully it will be completed this weekend.
