I don't know why this part seems so interminable, perhaps because I keep stopping to measure. I said at the end of the last entry that I had about three inches to knit before I start the decreases for the top - that is incorrect. Three inches is roughly the length from the wrist to the top of my four-year-old's pinkie, and a chunk of that is already in place from working the gusset. Mathematical errors are inevitable; I've never been interested in the subject.
It is incredibly difficult to get a four year old boy to keep his hand still. The actual measurement was a shade under 2.5 inches from the cast-on stitches at the gusset, or 7.375 inches from the bottom edge of the cuff.
