The first few are all dyed with very little water, and normal temperatures. The colors come out much more intense. The patterning comes from crinkling the fabric into a loose pile. The fabric was dyed with the exact dye batch that I used for the snow dyed pieces I shared earlier.
Please excuse the wrinkles, my ironing board doesn't work very well. I really need to get a custom ironing surface designed for fabric rather than clothing.
