I recently took a workshop on dyeing with coastal mushrooms and i took some photos to share...
The top yarns here are dyed with a fungus called Dyer's Polypore and the bottom is dyed with Sulfur Tuft mushrooms, the different shades are from the different mordants used. we did a dyebath of fresh mushrooms and dried mushrooms for each with different results.
In the pot is a dyebath of Lobster Mushrooms with the first two hanging in the tree.
Lobster Mushroom dyebath cooking..there was a quilter taking the workshop and she had some fabric samples in there.
Yarns dyed with Lobster mushrooms
we also did 2 more that i didn't get photos of- one with Velvet Pax that came out dark brown and one with Red-gilled Dermocybe that came out pink.
It was really cool...the mordants kind of scare me though, I want to learn more about them. I'm in BC Canada on the sunshine coast...but there are different mushrooms you can probably use in all parts of the world. A woman called Miriam Rice from California has written a couple books about mushroom dyeing.
