Scouring with Orvis

One of the most important prep steps in mordanting is scouring the substrate. In this case Crown Colony wool is the substrate. It’s been in the Orvis bath to take out spinning dirt and grease. Next up my husband is helping me with the mordant bath of alum sulfate and cream of tarter. The dyestuff will be my weld that we’ve been harvesting this year. I’ll run a comparison bath to my dried weld leaves from last year. At least that’s the plan for now!
