My brother really wanted an argyle sweater for christmas. I chickened out and didn't make him one. I did, however cave to a fortuitous combination of queued pattern and stashed yarn. This argyle sock pattern is written for a sport weight yarn and I had quite a bit of it stashed from some a fair-isle folly a few years ago.
The details: the yarn is Brown Sheep Nature Spun Sport for the main colors. The purple CC is Dalegarn Ull and the pink/orange CC is Valley Yarns Franklin. They're currently on size 3 dpns, but I used a short circular for the flat upper portion.
The intarsia and duplicate stitch are not the hard part of this project, but you need to be very precise in sewing the many seams with mattress stitch. That can be a little tedious. It's actually going surprisingly fast, and I'm looking forward to wearing them!
