This is my process for multiple skeins. I never promised KISS. but this works for me. i can do 2 roasters or 24 skeins in 4 hours. or i could do 4 skeins in 4 hours. what would you do?! except for boring beige, this is my process:
In the roaster, i have 3 rows with 4 jars. Each row is 1 hue.
Then I assign each column is a DOS. There are 3 jars in each DOS, 4 columns with 3 DOS. Each column would be one DOS.
I put my salt for each skein in a weigh boat prior to adding the dye to the water. My system would be to take the top boat of salt and put it in the top jar of the column. i had to come up with ways to remember! also the salts ontop of the soda ash stock because it goes in first!!
I did end up making stocks of soda ash, because i was running 2 roasters. To do this, i determined how much water went into a quart jar, and did the math (!) for 0.25, 1, 2, 4 for the soda ash. Once they were mixed, i capped them and put the 4 stocks in a pot on the stove to keep them at 60ºC. When i was ready for the soda ash, i weighed out the amount needed for each skein. I would do all of the first column (0.25). then move on to the next column (1) etc.
Sorry it took so long to post this! but i imagine you understand.
