Oh the fun!
Dyeing is one of my favorite things to do. I’m constantly figuring out different ways to do it, attempting various effects and new color combinations.
There are many methods for dyeing wool, one method is to dye the wool before it is spun.
Many people like to dye yarn after it is completed, as I did with this one:
But usually I prefer variations of color within each single strand and a difference of color between two strands that are plied.
I’m sure you’ll develop your own favorite method and effect too!
There are many, many techniques for dyeing wool, and there are many good books to give ideas and hints. My advice would be to start with your public library. Once you learn a technique that works, experimenting with color variations has the potential for many years of fun!
