Thanks we do have black walnuts on the family farm.
Jan I was thinking more from the farm than baking soda but its incredible that it reacts that way with oak and not other woods. Definitely worth a try as a frugal option. I have some oak I've been wanting to put to use any way.
Now I want to find out what reaction causes the color change there!
Mike I am not familiar with hopi sunflower dye but I'm sure I could get some seed from baker creek or Johnny's or maybe high mowing. It sounds like a really interesting
sustainable option!
I had been considering buying raven Ransons book on flax textiles already so linseed oil would be another reason to so some flax thise season.
