I just finished knitting up a tam....one of the Three Tams pattern. I knit Tam C, because I liked that pattern the best. It was a fairly easy knit, once I got reacquainted with holding 2 strands of yarn. The main color of my hat (the blue) is Cestari Traditional Collection wool yarn, and the contrasting color is Noro Kureyon.
I ended up tinking (taking stitches out...tink spells "knit" backwards) back and re-knitting the same several rows several times, which got to be a chore. Turns out, the pattern did not say to move the marker before each decrease row, but luckily many people left notes on the Ravelry page explaining the issue.
I love how it turned out, and I think I'll enter it in our county fair coming up in August!
