The opposite of instant gratification... here are the results of the lightfastness test I set up last January for yarn I dyed in autumn 2020. The top lollipop stick of each pair has been sat on my sunny studio window sill for a year. The bottom sticks are the same yarn that’s been stored in a dark box during that time. The first photo shows the more fugitive colours - sloes and red cabbage are particularly unstable. The second photo shows dyes from trees and herbs - I’m surprised how little those colours have faded in the sunlight...
