While visiting The Manor at Hemingford Grey (see entry on Bracket Fungus for more details) I saw a wonderful spreading yew tree (Taxus baccata) in the secret garden. This reminded me that yew wood shavings can give lovely orange & rust colours in the dyepot. So if you know a woodcarver, or have some other source of yew wood shavings, collect about the same weight of wood shavings to fibres you wish to dye & start off by pouring boiling water over the shavings & leave them to soak overnight.
Then simmer the shavings for about 1 hour & pour off the liquid to make the dyebath. Use wool mordanted in alum – I usually use 10% alum i.e. 10gms alum to 100gms wool – & simmer the wool in the dye solution for about 30 to 45 minutes. Leave to cool before rinsing. You can also experiment with colour modifiers for variations in shade. (See entry on Dahlias for further details).
