I love arm warmers, especially because most of my coats are 3/4 sleeved, and I love a layered patterned look. I was looking around online at free people (I look for both inspiration and for a good laugh, because, really) and saw t-shirts with arm warmers sewn into the sleeves. At least that's what it looked like to me. This reminded me of my favorite socks, and so I grabbed my favorite cozy shirt and one of my best pair of wool socks and cut into them, risking ruining both, or scoring a double-win. I'm happy to report it was a double win. The socks sewed beautifully to the sleeves. I cut some length off the sleeve first then stitched, right sides together, with a small zig-zag. I have no idea if this hack is on the interwebs. I did a quick search just now and only found turning sweater sleeves into boot cuffs, but not sewing socks onto sweater sleeves. Easy, fun, and hobbit-chic. (Hence the middle earth mug.) I plan to make more. My socks are getting nervous. Or maybe not, maybe they like being sleeves! I think they do.
