We'll start around 10'ish and use this lovely, yet primitive, solar oven to set the dye.
The oven works pretty well. In a test run in the evening, the temperature rose from 80 to 136 in 20 minutes. It topped out at 136. I'll spray paint the top black to help. I'll make a test run this week.
People need to bring around 4 oz of their favorite protein yarn or roving for painting. We'll use Kool-Aid or similar drink-ade for dyeing. Brand will not matter. Pick up 4 to 6 packages of 2-4 harmonious colors.
I asked my scientist husband and kids to do so...I'll live with their choices. Let's just say it's interesting. It'll work. I know who chose what colors.
We'll have plastic wrap, sponge brushes, cups, and vinegar.
