Dye plants.
I can swap or pass on Oak apple galls and Walnut husks for mordanting wool and dyeing dark brown. I can offer Madder roots towards the end of next summer (2016). I have Pomegranate dye in liquid form and Alder Buckthorn will be available a bit later this autumn (it dyes yellow/green/brown depending on the water) I can pass on Sumac in liquid form for a pale brown.
I would like to get hold of Dyer's Weld and Dyer's Alkanet
