So far my method is to make the bundle...it seems to work best to use moist wool, sprayed with a weak vinegar solution...boil, or simmer it for about an hour, hang it up to drip dry, then let it dry in the oven, where, due to the pilot light, it's quite warm, overnight. Then pop out of bed and open it before breakfast.
Here are a couple drying and looking prehistoric:
This is today's bundle which is partly clamped with old pennies and round plastic shapes to see if that will yield something interesting:
Now, some results. These are 4 light wool scarves (ordered from Christine Mauersburger's Hank and Spool), dyed with an assortment of leaves...the browns are from my backyard leaf fall; the wonderful orange imprint comes from local eucalyptus leaves. (The persimmon is from the tree in the front of the house. I haven't yet figured out how to persuade much color to come out of its leaves.)
I have been reading and re-reading India's book Eco Colour for guidance about all this, and especially about Eucalyptus, of which there is a LOT around here. Not all of them are beloved by the local inhabitants, but by the freeway grows this tree, a Eucalyptus Pulverulenta (I think), from which I harvested windfall, yielding the results above:
And here is Miss Gilly, watching the crows circle around the persimmon tree. The fruit on top is quite ripe and the birds are feasting regularly. Also the raccoons. But so far no one has bothered the ones I set out on the window sill to ripen. What a harvest this year!
