The process itself is pretty simple, and can be found just about anywhere online. We took two chairs and set them on either end of the dining room, and KB wrapped two skeins of yarn around them, creating one really long skein. AB did the same with two more skeins. Each of them used rubber bands to tie off where they wanted the color changes to go, and we set them to the side for the next time she could come over.
AB came back over today, and we got to work as BB's tea party was wrapping up - speaking of, it was absolutely adorable, and she and her friend had a great time. At any rate, we promptly got to work on mixing up Kool-aid in mason jars, and putting them into the pressure cooker, along with a couple inches of water.
