I've recently started photographing my yarn with crayons. Why?? It is to make sure you have a good idea of the colors in the skein. If you see a crayon labled Sunshine Yellow, but on your screen it looks more green or gray, you can color correct to know what your skein really looks like. It is amazing the difference between screens even between different mobile devices. Thanks to these Crayola cues, you will get the best idea of the true colors you will be getting.
Peace,
