Linda J is dyeing roving for spinning. Linda K's roving is in the foreground.
The fibers we are dyeing have been soaking in an acid (citric acid) solution to bring their pH down to 5.0. We can then paint our dye stock solution on the fibers and nuke them in a microwave (very carefully, can't set the building on fire!) to set the colors.
Right, Kay S is painting yarn and wool fabric.
Right, Howard - I mean Linda K has her roving ready for the microwave.
