Two new things today with acid dyes on wool yarn

Today I overdyed the raspberry I did yesterday to see how acid dyes do when absorbing more dye on top of what is already there. Not a problem. Now I have the color I originally wanted. So far, I have not found any drawbacks in the system I am using or with the dyes. I even tried to shock the bit of yarn on the left by rinsing in cold water right out of the hot dye bath. Nothing.
Which brings me to my very own wool joke- "How do you shock wool? Sneak up behind it and yell 'WOLF'!"
It's all good.

Next test was to see how light I can make the dye color. Everything up to now has had maximum absorption of the dye color.

To this dye bath I only added 1/64 teaspoon of sky blue dye. I got a little worried about 2 minutes into it and added another 1/64 teaspoon to make 1/32. The color is beautiful.

What I learned from this experience is that as the water heats, so does the color. It probably would have been okay left at the original amount but I do like this value and will use this measurement again on other pastel colors.

Since this is yarn my daughter will be using, I intend on overdyeing this a deeper blue tomorrow. Stay tuned.
