For me, the most interesting part (aside from how simple the actual pattern is yet how complex it looks) has been turning the heel. At first I thought I read the directions wrong because only a few stitches are knit at a time. However, with some faith in the patter (and now some hindsight), it makes sense. Everything is pulled together in a sort of zig-zag fashion, where every row incorporates an extra stitch until they are all accounted for.
Now with all the talk, I'll give you a picture of my only knitting WIP, my jaywalker sock:
As for Sunday surprises, as I was typing this up, I heard my dad yell "There's a hummingbird in the garage!" Sure enough, there is. We're having trouble getting it out since the bird won't stop flying right near the ceiling, but we are trying. I have a few small pictures that aren't detailed, but I still thought it was an interesting thing. Out of all the animals that we've found in our garage, this is the first time I've ever seen a hummingbird there.
