i really don't think static electricity is part of the issue with sticking to wall. i lived in wet non staticy pacific northwest with felt design wall for 14 years. open deck door around corner thru door of sewing room. fil called our place "pnuemonia point" because the cold north pacific winds blew in off the ocean continuously. i now live in dry desert clime. static is so bad i have to be careful petting the kitties. no carpets. my felt (wall) curtain only dislodges blocks with the big fuzzy tail waggers' help
