I like the Vogue Stitchionaries, too, and I just ordered the Knitter's Workshop by Elizabeth Zimmerman....I have Knitting Without Tears and Knitters Almanac by her, I can't wait til I can afford to get Knitting Around by her!! I'd really love to have the PBS video that goes with the Knitter's Workshop.
Most people really LOVE Vogue Knitting too. I haven't been able to get it yet, and there are 4 Barbara Walker "treasuries" of stitches" books--I have the second and it's really good. I have about 30 knitting books--and I don't want to part with any of them, truthfully!! I guess Vogue Knitting or the Knitter's Bible by Claire Compton would be 2 overall good ones if you can only get one!!
