Longer soaking might even produce darker dye bath. There is a lot of pigment left in the dye bath and dye can be stored in jars. Fill to brim to avoid mould forming. it could also be used to add to creams and golds to strengthen.
Silk takes up the brown dye bath quickly but keep turning and agitating occasionally while soaking. (I don’t boil Ahimsa silk as it would roughen surface) Soaking is adequate for obtaining a reasonable colour.
Silk samples show differences of colour between Walnut dye and Comfrey dye. Walnut dye result is the darkest gold, more of an envelope buff tone, achieved with natural plant dyes.
Collecting Dye Plants Along The Tarka Trail, an old rail track Barnstaple to Bideford was my 10 mile route for foraging; using Jenny Dean’s plant spotter book. Late summer finds many of the traditional dye plants along grass verges, especially in areas untouched for ages.”
Processing for dye bath
Authors Samples – I chose mostly pink and lilac dyestuffs which I tried to arrange in circular patterns, but this process is completely unpredictable. Next time it would be interesting to make dyestuff arrangements in circular tied bundles or with elastic, similar to tie dye techniques, form snowflake type designs.
