Hot and Cold
The record heat of the summer was a reminder that
coloring utensils do not like extreme temperature swings.
Years ago I was teaching in a classroom without AC, and the crayons melted!
If you need to keep your utensils in a hot or cold car,
be sure to put them into some kind of insulated carrier
to protect them from the extreme temps.
Some ideas include:
Insulated grocery bags
Even double bagged paper grocery bags
Place them under a blanket
