I thought the headache was better at this point, but you can see that straight had nothing to do with how I was seeing! I was using a STRAIGHT-EDGE ruler too. sigh When we laugh that I can't see straight, take it literally!
I've not felt up to knitting, even garter stitch. Even now it is a bit beyond me, which is "interesting" as I teach knitting again tomorrow. Watch for pictures! I hope. We may be busy enough that I don't take any!
