Went out into the yard and picked "feathery" ferns and leaves. The boys dipped them into water and placed them on raw eggs.
Covered them with cheesecloth and secured it in back with a wire twistie.
Placed them in a pot with the chopped up cabbage and about 1/4 cup of white vinegar.
Another pot with the chopped up beets and about 1/4 cup of vinegar. Simmered a couple of hours and then we left them in the pot overnight. The last time we looked at them before bed there was no color.
The next day when we removed them they were beautiful After they dried we rubbed them with cooking oil. The blue was from the cabbage and pinky brown from the beets.
