Gentle Spiders,
I had my first begriming beginner lace student - the first in a long time.
I wanted her to come over for a lesson before she ordered any supplies to
get a clue of what she was getting herself into, and what was available.
She was able to get both Doris Southard's and Pamela
Oofph!!
Tough choice
Either you're comfortable, and can focus and be in your element, or...
Your student is comfortable, and able to attend to his/her teacher who
is paying for the air conditioning on his/her behalf, but not as
comfortable.
Short run... turn on the AC... to low.
