"Bah!" said I, "It will block out." And I kept on knitting, a few rows here and a few rows there.
Inner Knitter tried a different tactic. "Use the tape measure."
I heard that one for a few days. Finally, I used the tape measure. As usual, inner knitter was right. Last weekend, during Sunday's football games, I frogged the 3/4 of the way knit wrap, and started over. This time with 102 stitches. If it doesn't pan out this time, I'm picking a different pattern.
The moral of the story; Sometimes, the Math lies, especially if you didn't block the swatch.
