We are very pleased to have been asked to contribute some naturally dyed wool to Jorvik Viking Centre, York. This is part of their redevelopment after the devastating floods in 2015.
Basing some of these on funds from the Coppergate excavations, we have experimented with mordanting with Lycopodium clubmosses. Below is a photo of a range of colours dyed over lycopodium mordanted wool.
The single bright yellow is Alum mordanted as comparison.
