I started these a couple of months back actually, but finally - done. H's space invader socks.
I started knitting intarsia in socks because someone told me it is very difficult. It isn't (I have knit much larger intarsia patterns than this!), but it is extremely wearisome to deal with all the ends, so I don't think I will do it for quite a while now...
Here you go, documentation of the finished product. Arctic wool yarn on s5 DPNs.
