Last night I started making a pillow for my mom's birthday this weekend, with the help of Jenn and her chainsaw sewing machine.

Somewhere around the third time I sewed two pieces together inside-out, a muscle underneath my right shoulder blade started to hurt. This is the same muscle that frequently gets sore when I play guitar for more than half an hour at a time.

Then I figured it out.

That's my "I wish I was better at this" muscle.
