I currently have four washboards hanging on the wall in my laundry room which, occasionally, are used for their intended purpose. I purchased one of them which was manufactured by the Pearl Company because my much loved and missed grandmother’s name was Pearl. Another was gifted to me by my children. They thought it was unusual because of its small size. It’s actually a lingerie washboard with very small ridges designed to be gentle on a lady’s delicate under garments. I’m still on the hunt for a washboard with green tinted glass like the one my grandmama had. They are, evidently, a rare beast. I admire the use you put a falling apart washboard to. Should I find one in dilapidated condition, I’m going to have to borrow your idea!
