I spun a sample of silk and alpaca blended fiber (about 2 yards worth), wrapped around my hand, tied, then dipped each end into a concentrated mixture of each color (one packet to 6 ounces water).
Zapped in the microwave for 1 minute, took out, dunked again.
Zapped again, took out, filled with water (carefully), zapped again.
Then I took out the fully hot batch and let it sit for five minutes before rinsing in hot water and winding onto my home-made PVC skien winder. I love the varigation of orange and yellow!!
