What’s the etiquette for an add and pass that has had an unintended alteration such as spills? I wish I was asking out of curiousity, but there’s been a pet related mishap. The two sheets effected seem to have dried ok, and it’s nothing hazardous, but the grossness factor is making me hesitant. At the same time, I don’t want to just toss out something several people have worked on. Photograph for the sender and toss it? Cover the stained bit and send it on?
