I would say that sometimes putting a damp pillowcase right in the enclosure is not an option (as in my case). I use scott shop towels as substrate so when they get wet, they stay wet. I change them often but I don't see what is wrong with either soaking in a separate tub or putting a damp cloth in with the bp in a separate tub. What ever works for each individual I guess, as long as the bp is kept warm and the stuck shed is tended to.
