Finishing
Rinsing, Washing & Textile Care
Rinse your dyed fabric in an ample amount of water first, you will want to rinse out as much of the excess dye as possible. I find the color will morph slightly, but I prefer to get out as much color that is not bound to mordant as possible.
Then let the fabric dry without further washing for a few days. I find this helps set the colors & designs. Then using a very hot iron, (this is fine for silk as well, silk is a stronger fiber than we commonly think!) iron your piece to help heat set it.
You may then wash by hand or on a delicate cycle in your washing machine with a pH neutral delicate detergent or soap. Hang dry the piece and avoid excessive & prolonged direct sunlight to preserve the colors.
