I experimented with this video showing how I add a small amount of fiber into this style of dye vat (for more information on mushroom dyeing, please consider checking out one of Alissa Allen’s mushroom dye workshops). I add the fiber while it’s in a mesh paint bag (from a typical paint store). This extra step allows the fiber to remain isolated from the dye material without the hassle of decanting. In the video you can see me add in the fiber that was premordanted with alum (at 16% weight of fiber).
