one down for may

First OPAM project for May done and gone. My coworker gave me a week extra as his MIL's birthday is this weekend and she wanted to see them for that rather than Mother's Day. I was going to get the binding on last Saturday and do the hand work on the drive to Rhode Island, but the weirdest thing happened. As I was pressing I got a cramp behind my shoulder blade that wouldn't go away. It started around lunchtime and didn't stop until 9pm. Nothing I did would make it go away. I am not prone to cramps so it was very odd. No recurrence since, so I am hoping it was a one time thing. I don't have enough time as it is. I can't afford to waste more than half a day not able to move.
