Dyeing for Dummies: Natural Dye Poster Child-Indigo

For this Dyeing for Dummies, I have put not only myself but husband and daughter in the cross hairs of looking foolish, over exuberant, and dummy-like. (Side note, they had a blast and refuse to be called dummies.) We used all of Botanical Colors’ dyes and … Read more
