Thanks everyone. Will still think about it. We have not had any critter problems in our regular shed. It would be insulated with walls and I used damp x now in our storage building. The reference back to the member who actually bought one and finished it is what I want to do so that has helped. I will think about for a while longer. No hurry until we can't walk past totes of fabric. LOL I just need room and don't want the expense of adding a room to the house.
