This is the V Neck Cardigan from Knitting Pure and Simple, top down, pretty easy to do. The yarn is Berroco Remix, a blend of cotton and silk with a tweedy effect and very nice to work with. Last spring or summer I took a class at my LYS called "Knit Your First Garment". We made a vest with a chunky cotton, so it was quick to knit, and I learned a lot, but it really doesn't fit well because it's too big. This is my first knit sweater, and it fits just right. I'm tickled.
I used Noro Silk Garden, which I think is awfully itchy, but the colors are every bit as intense as they look in the photo. One of my knitting pals made a scarf in Noro Silk Garden, and it was considerably softer than this sweater, so it must soften with use or perhaps laundering.
I'm tempted to make one of these in an adult size for myself, but Zimmerman only gives you a vague description of the math involved to make one, so it seems you have to write the pattern yourself, which might make my head explode.
The Quick Slip Cowl, which takes about 10 minutes, is knit with Berroco Brio, a chunky weight yarn. It doesn't really take 10 minutes, but it's a pretty fast knit. I've never been much of a scarf person, but it's been arctic in the northeast and getting colder still, and it's very nice to have a bit more warmth around my neck.
I don't think the pattern is particularly well written (but English is not the author's primary language), but neither do I think it's terribly difficult. It only took a couple of feathers to get the hang of it; but after 8 feathers I can watch tv but not carry on a conversation. I used a fingering weight yarn with alpaca in it for the main color and a Mille Colori for the feathers. It's interesting to see that the two colors in the yarn are alternating every other feather. An interesting pattern indeed.
