I did my first LWI the other day and used the advice on this forum for setting it with Soda Ash. IE: 1 teaspoon soda Ash per cup of dye water used. Then pouring directly over fabric still emerged in dye bath.
When I grad dye I set the dye by emerging the dyed fabric into a clean solution of soda ash and water.
My question is, would submerging the lwi'ed fabric into a clean solution of soda ash and water work as well or is it necessary to keep the fabric in the original dye bath and pour the soda ash solution over it?
