Mostly Mittens: Ethnic Knitting Designs from Russia (revised edition)
This is an excellent compendium of geometric patterns from the Komi people of Russia. As you can guess from the title, the book focusses on mittens: 35 mitten patterns are included, along with a few hat patterns. Not all of the mittens call for Shetland jumperweight yarn, but they are all knit at an appropriate gauge for Spindrift. But the motifs themselves are worth the price of the book–they are very easy to knit and lend themselves to allover and banded designs. (The previous edition was entitled Knitting Marvelous Mittens).
