Definition of stupidity: knitting a sleeve that is plainly not wide enough for an upper arm.
Definition of a total loss of common sense: knitting the second one exactly the same, without checking the sizing.
Spent some time trying to figure out why the next size up was 57 sts and not 43 + 8 as I was expecting.
But! BUT! I got my Ravelry invite, so I don't care. Been playing about with it this morning and it is very, very cool!
