I had a lot of fabric including batiks stored in the plastic containers for years. No problem but they were in the closet in the house with a/c (air controlled) You should be ok since your location states OKlahoma. You can go to the dollar discount stores and some home improvement stores and pick up or go online to purchase silica moisture absorbing beads. You shouldn't have any trouble. You should be ok with the under the bed storage containers for fabric for 2 quilts. Make your own quilt kit and put it in them including needles and thread.
