Well,Lightning, hanging them in the house is fine ,but we don't have enough room to hang all of them in the house at once,we aint city folks,we get our clothes dirty on a daily basis. So,we can hang a few pieces in the house for quick drying,the rest goes on the line to be brought into the house later,replacing the dried pieces on the rack & so on. We don't do laundry at 6 PM & hang it out overnight expecting it to be dry by 6AM !?!?!?Last load might be 2-3PM & then hung on rack in house overnite to dry. Maybe our outdoor drying success is a special blessing from God, as He might see us as you do,... too simple to understand that freeze-drying won't work.
