this is the third and very ambtious attempt!! i created two of these coulmns off site in my shop do to the fact they are not allowed to be permenent.they are actually sleeves that slide over the walls even the "bases" are sleeves to go over there base board. the mud was better as i got damn near 2" in most places. cple four ways and lotsa rounded edges. overall i am pleased with them and they draw tons of attention in my little store space.
