As someone who grew up in Anchorage, I have a double appreciation for this book. I recognize many of the patterns from traditional Native beaded works, and I often passed by the Oomingmak company in downtown Anchorage. I didn't knit at the time, more's the pity! Although evidently the Oomingmak knitters are a tight lipped bunch. One gets the impression from Druchunas' book that she had a difficult time indeed in getting the Oomingmak knitters to talk.
As a rule, knitting books are all aimed at the beginning knitter. Don't get me wrong, this makes sense. Numerically, there are more beginning knitters at any given time than there are intermediate or advanced knitters. (All intermediate and advanced knitters started out as beginning knitters, after all. And not all beginning knitters stick with it and make it to the intermediate level.)
You might be tempted to try knitting some small toys as Christmas presents. I recommend against this, unless you have a lot of experience with knitting toys. Even though knit toys are small, they can be surprisingly fiddly. I suspect that if you clocked most knitters, they could crank out an entire worsted weight hat in the same amount of time it would take to knit a small toy.
Most of the time when you are looking for a stranded colorwork motif, you have a certain number of stitches you can devote to the motif. Unfortunately, this Stitchionary doesn't classify the motifs in any useful fashion. Short two color motifs are jumbled up with long two color motifs in the "two color" chapter, and short multi-color motifs are jumbled up with long multi-color motifs in the "multi-color" chapter. I dare say that organizing the motifs by the number of colors involved is one of the least relevant ways for the knitter.
