The pattern is from Drops, here it is in English og her er det på dansk. The Danish version actually says it will look good on a little girl, but I think it is unisex enough when knitted in green:
The legs are knitted separately in the round, which probably makes good sense, I'm sure the pattern would look bad sewn together. But it is quite problematic to put the legs together. OK, the pattern says to knit 2 cm back and forth to make it easier, but it doesn't make it easy. Also, a circular needle that would be small enough for this number of stitches would be annoyingly short to knit with, so I had to continue with dpn's after putting the legs together. But because the legs were pulling in each opposite directions, there are some ugly transitions although I pulled all stitches really tight. Oh well, here's to hoping it goes away when washed.
