We love the children's book author Steven Caney. Katie and I grew up with Kids' America, (it is also heartily enjoyed by our boys):
Despite the stressful cover photo, (Stressful for me, maybe innocuous for you) this book is awesome. It is stuffed with tons of American history and activities-how to make old fashioned food, clothes, and toys. My favorite-deciphering hobo sign language.
Finding blackberry vines in our new yard inspired us to try the berry ink from Kids' America.
Push 1/2 cup berries through the side of a strainer. (We used a tea strainer)
Add 1/2 ts salt and 1/2 ts vinegar.
Add a tablespoon or two of water if the ink seems too thick.
Apply to paper! Now, the book shows you how to make wooden pens and quill pens. We used newfangled store bought paint brushes with great success.
My experience with dying fabric with natural dyes leads me to assume this ink/paint will eventually fade to brown, but for now it is pink!
