Acid Dyeing for Silk
Measure out 1 litre of warm water into a dye saucepan (stainless steel or enamel is preferred as aluminium, copper or iron containers can all affect the shade of the dyes.)
In hard water areas add 3gms CALGON PT to the water and stir to dissolve.
Add 1tbsp of lemon juice/vinegar (fixing agent) add to the water and stir to dissolve.
Paste about ½ tsp of dye with a little tepid water then add boiling water to dissolve. Add the dissolved dye to the water in the saucepan.
Add the wet fabric to be dyed and stir gently with a wooden spoon. Bring the pan to nearly simmering. Leave the silk nearly simmering until the required shade has been achieved.
Wash as normal to release any surplus dye.

As newcomer to silk painting I have found Shirley's instructions have been invaluable. I have now successfully dyed 5m of silk velvet - black, and made a full length cloak. I have just finished 7m of silk with a salt effect finish, in purples and wine red - and my daughter's prom dress is looking amazing. Don't be afraid its really fascinating!
