Another possibility in some areas of the country is spray foam. A friend showed us their basement where foam was sprayed on walls and ceiling which made the house warmer and the basement dryer. We also have an old house with round rock foundation walls and we are going to look into doing that. Since our basement floor is dirt, only concrete under the furnace, and part crawlspace, it still won't be usable for much, but I think it would help the dampness from going into the house. Of course sump pump or dehumidifiers can also help in some situations. Good luck. Be as creative in your storage as you are in your quilting. I just found good size underbed storage boxes with casters at a very good price at Family Dollar. This is not a "$1 store" but a discount chain in some areas. I'm rearranging my stuff into the "Harry Potter space" which is a closet under the stairs in the living room. Some stuff will go under the beds. Not ideal, but much neater than it was before.
