I paid a visit to the CYCA's website the other day to look at their charts for body measurements and standard sizing, and was pleasantly surprised to see that they have added measurements for upper arm circumference and armhole depth to all of their charts-- Baby, Child/Youth, Man and Woman.  I also seem to recall that they didn't used to have measurements for waist circumference...is that possible?!  Anyway, they do now.  They also have a Foot Size chart, which I don't recall seeing before-- although I'm not much of a sock knitter, so maybe I just wasn't paying attention.

If you've never used these charts before, they are very handy for pattern writing, and really essential if you want to write patterns for most publications.  Even if you have no interest in creating patterns for different sizes, it's nice for you as a knitter to know how your own measurements differ from the "standard" (and almost everyone has a few non-standard dimensions!); it will be helpful in predicting how you might need to adjust pattern instructions to better fit your body.

Important note to all Fern Fitted Shell pattern purchasers:  I just added a new errata, which is now incorporated into the pattern pdf.  If you'd like a corrected version of the pattern, just email me.
