I have learned so much from this simple post of yours! Madder? Never even heard of it. Cleavers? As if there was a faint bell ringing somewhere. Okay, the Rubiacea family I have heard of. But that this plant was responsible for the red dye all over the world, (and thus the British Redcoats) ... wow! Why is this knowledge not more common? Lovely photos by the way of you and your textiles! Thank you so much!
