A Sleeping Makenna Is Affecting My Crocheting Measurements

I am almost finished crocheting a 15 by 15 inch square for a Facebook friend.

As I went to measure it Friday, I found out that what was 15 inches at the bottom, was 17 or more, at the top.

Thus, I will probably need to rip out part of it, and re-do it.

I think the problem is that the cat sleeps on my arm, and so the crocheting is too loose...or something.

We won't even go into the fact that sometimes my hand goes numb.

Thanks, Makenna.
