Our sons (2 and 5 years old) helped me to koolaid dye some sock yarn to be made into socks for them. R, our 5 year old, did the purplish/turquoise ones on the right. I did most of the ones on the left, but E helped put a few spots of color on. Great fun and the results were fantastic! I'm thinking I need to put them to work dyeing all my sock yarn! The yarn was Opal Uni, an off white color.
