There are not too many mitten patterns that I find worthwhile - but I really like Eunny Jang's pattern for the Anemoi Mittens. In fact, it's the only pattern (so far) that I've bought off the internet (Cheap? Yes. Discerning? Also yes. There's a lot of good free patterns out there!). This was my first pair of Anemois, finished at the end of April, just in time for...spring.
I loved the yarn (Koigu), and I loved the colorway of the variegated skein (I like to call it "Burnt Toast & Juniper"), but when I put it together with the cream, the swirls and the crosses on the back got kind of lost - I even tried switching which hand held which color, and it still came out a little muddy. They were my first fair-isle project, and my first time using Addi Turbos (sizes 2 and 1!), and I was very sad when I bound off the second thumb - no more Anemois!
When a friend at work expressed a desire to have a pair of her very own, I was happy to haggle with her (let's face it, they're fun, but if they're not for me or family, I'm not likely to want to do it for free). She's an excellent beader (beadress?), so I'm making this pair for her in exchange for a set of dangle-free stitch-markers (here's an example). I'm using Paton's Kroy, my trusty Addis, and I'm having a blast.
