These two were dyed using Logwood extract. I didn't leave these in as long as recommended because I like the color where it was! I also dyed some wool some with the shorter dye bath and some overnight. The overnight turned very dark purple. I've used the same heavy duty blue gloves for four years the logwood became permanent where all the other dyes didn't. Even when the wool was rinsed till clear it left purple halos on my drying frames. Really different than I expected.
