...Sweater pieces lie, also.
Look at the lovely progress I've made on my sweater back! I worked on it at SnB last night. The directions for the part I'm on now instructed me to work in stockinette until the armholes measure 8.75 inches. Okay--I can do that! I measured periodically to check my progress, and I started getting excited when the tape measure said 7.5. I did math and figured out that I should only have 8 rows to go. I did 8 rows, measured again, and got 7! WTF?
Grumble grumble. I laid it on the floor, spread it out, and remeasured--this time I got something like 7.25.
I kept measuring and remeasuring, and I don't think I got the same number twice. So now the sweater back is in time out. As Robyn suggested, I even put the bag in the corner.
Stupid sweater. I hope that it decides to behave.
