Personally, I'm pretty disappointed that the pattern has so many errors. Infact, there are more errors than are listed in the errata. Also, there are some stitches: Indian St, SK2P, 4-RC, 4-LC that could've been quickly explained in a key on the pattern. No such key is listed in Vogue. It wasn't hard to google the info for the stitches of which I was unfamiliar, but it still would've been nice to have a key with the pattern.
I am just beginning the the outer ring and have frogged a couple of times because you really need to count and the kidlets have other plans for me Also, if knitting this pattern, I suggest that you knit the outer ring on straight needles (I'm a circs junkie myself). Fortunately, I am knitting this with a group of ladies and I've gotten feedback from some of the faster knitters that straight needles are a must for the outer ring (I concur) and learning to cable without a cable needle is also handy and faster.
