9 hanks of wool

These are my 9 hanks of super wash Merino.

Here is the list of all nine

2 - Scoured

2 - Alum

2 - Neither

1 - Undyed





Scoured means the hanks were washed in a wool soap to clean any dirt or chemicals from the wool. Alum, (Aluminum Sulfate), is used to help Brighten the color and allows the color to not fade from natural light and washing. I want to know how each of these affect the color, so each of the three goes and soaks in the dye.
