Unfortunately, I did not follow the directions very well. For some reason I decided that casting on 75 stitches was not enough, so I cast on 90 instead. This made the blanket very very wide - about 49 inches. I then knit 102 rows, which made it 34 inches long. I had been hoping for a finished blanket that was square, but by the time I got near the end of my third ball of yarn I could see that if I did make it square it would be gigantic so I stopped.
The hardest part of this blanket was alternating knitted rows with purled rows. It seems to take me twice as long to purl a row than to knit one. I probably could have finished it a lot faster if I had just knit the whole thing.
It may not be the prettiest blanket ever, but hopefully my friend (and her baby!) will like it.
