I've been back in the States for almost two weeks, and I think I've finally readjusted, more or less. There's still the risk of reverse culture shock down the line, but I'm feeling less out of whack than I did when I first got in.
Anyhoo, I'm waiting for most of my craft supplies to reach me. Since sending packages by ship was the cheapest option, that's how I mailed them home, but it takes a month or more for the boxes to get here. Fortunately I ordered a ton of yarn while I was still in Japan that my mom never sent to me, so I do have a couple projects in the works right now, ranging from complicated (a cabled afghan that I'm pretty sure has a few errata in the pattern) to simple (a 1X1 rib Gryffindor scarf).
