Transformation

This fairly boring and not very expensive sock yarn that at some time was bought at the supermarket has been transformed into this:
The picture does not do it justice at all, and I cannot seem to get it to look like the yarn itself. It is deep greyish green en turkoise, and I love the way something boring can be turned into something yummy by a little work, two bottles of food colouring and citric acid. What a difference. If I can get over my sock fear, maybe they'll turn into yarnissima's firestarter.
