I have an elm hollow form that has developed a bright yellow color on one side while drying. I've never seen this color develop before. It's on the inside as well so assumption is that it will have to be part of the final look. Anyone seen this before? Some new kind of mold? I dry my natural edge and hollow forms in paper bags so plan to throw away the bag this one was in. Maybe I need my drying bowls to practice social distancing now.
