I took Helen's advice and did a swatch, after completing two rounds of Chart 1. And yes, I have been knitting too tightly.

So here's my progress, after switching to a size 4 needle. It's much easier to knit; the stockinette parts look prettier, even before blocking; and I'm moving faster through the charts.

Today it was over 100 degrees in Chicago, heat index of 110. Good weather for staying indoors and knitting. Even my dog didn't want to be outside.
