Knitting a Toasty

I love the vague shorthand that is often used in knitting. For example, in a fingerless mittens pattern called 'Toasty', she uses a 'CO'... now, 'CO' could mean 'cast ON' or 'cast OFF'... I assumed it meant cast OFF. It didn't. If you presume 'cast OFF' you get this:



Let this be a lesson to pattern writers, please include an explanation of your shorthand so those of us who don't have telepathy can know what you mean. Tah.

Other than that, I have been ok with the pattern, admittedly, it's my first glove ever, perhaps that's why I feel so frustrated with the 'cast On' 'cast Off' issue. Crochet is 'chain' to start and 'fasten off' to end. No confusion there.
