I did find a few colors of the Soft Chunky at my semi-local yarn store (40 miles away but, in Los Angeles, that is not a big deal) and I bought enough pink (beautiful color!) for the Rockefeller Sweater. My daughter loves that pattern, so I got the same shade as the photo in the book. I also picked up one skein of Sea Foam and one skein of French Grey. Both are beautiful colors. The French Grey is really pretty and I don't usually get too jazzed about greys. I can see the French Grey paired with just about any other shade for the Marilyn sweater.
When I was at Knitty City, they had a few of the Twinkle items in the store display and I got to try on the Rockefeller Sweater, which is the only item that caught my eye from the book. I think it was the largest size (no size indicated on the garment) and I'm a petite xs/s so it made me look like the Michelin man. I think the Rockefeller sample was also longer than the one in the book because it hit my knees.
Knitty City also has (had?) autographed copies of the book. They had lilac, light gray, that neon salmon pink from Rockefeller, and perhaps a buttercup yellow.
I have a half-finished Rockefeller cardi heavily modified made with Debbie Bliss Cashmerino Superchunky and I'm debating if I should finish it--I need to divide for the arms. I don't like the way bulky knits look on me but it's too soon to tell with my progress.
Beware, the chart is wrong for one of the cables, just compare with the written instructions and for the other cable, the chart is correct and the written instructions are wrong.
40 miles is local for you?
I'm spoiled living in NYC--Purl Soho, Seaport, Downtown, Suss when it was around, and The Point are all walking distance from me. Knitty City is probably 6 miles from my home but a 30 minute train ride. I could have walked from work but I went during the freak snow storm in mid-March. Then again, you've got gorgeous weather year-round with no threat of snow!
