Root Retting Method, A Short Guide

Leave the nettles in the ground till the spring, February/ May depending on the weather.

1. HARVEST
Pick the old stems, which are still standing, just as the new nettles are coming up. The old nettles will not sting you then, but the new shoots will, so you may still need gloves.

2. DRY
Store the stems in a warm, well ventilated place, ideally with some sunlight, like a green house. Keep the stems until complete dry, best of all leave them for a year or two!

3. BAKE
Fold the stems gently three or four times until you have a bundle small enough to fit into your oven. Wrap in a thin cotton cloth and bake in an oven at about 70°C, for an hour, or longer at less, until they become brittle. The bottom oven of an Aga or Rayburn works.

4. BEAT
Lay the stems, still wrapped in cloth, on a hard, uneven surface and beat them with the edge of a flat stick, similar to a cricket bat. Shake and wring your wrapped bundle every now and then, rearranging within the cloth so that the stems are lying parallel. You can also try putting the wrapped bundle through a mangle or place it on the floor and dance on it!

5. PICK OUT THE FIBRES.
Unwrap the cloth, and you will see that the fibres are lying together on top and the hard woody bits have fallen off. Pick out the fibres by hand.

6. CARD
with a pair of hand carders or a drum carder and make into rolags. The fibres are quite short, similar to cotton.

7. SPIN AND PLY
Spin in the same way as you would cotton but S-spin. The nettle fibres can be spun while they are still quite coarse - when the finished yarn is boiled with soap, it will become softer.
Also hitting the hank with a hammer or mallet works to make it softer.

8. USE THE WASTE
Blend the hard woody bits (left over in the cloth after stage 5) to a pulp and use this to make paper sheets and vessels.
