But, no coughing at all. So, when I got home, I opened up the door to the terrace and turned off the A/C. Nice. So nice. They air is very much clearer this afternoon. Even the BreezoMeter says 64 "good air quality"!!
I finished my crochet square and discovered that depending on what I wanted, it was too small or too big. Sigh. So I designed what I wanted, measured all the sides (it's a series of rectangles to make a vest - sleeveless cardigan) and now I'm ripping out most of what I did. It's complicated because cutting the yarn would ruin the color morphing. I have a bunch more to ravel - down to the purple.
It will be worth it in the long run. I hope.
