A neighbour gave me what he thought was a quilting frame that he got from his parents house when they moved into a home. I think they are curtain stretchers. I've never seen any but I remember my mom telling me about them. These consist of two long split boards with bent over nails at about 1 inch intervals. The cross-pies would seem to fit between these poles and are adjustable to size. I'm thinking the curtains were snagged (carefully!) and then the frame propped somewhere to dry.
Would I be a bad person if I just burned them. I already have two quilting frames and would have no need of the curtain stretchers. (If the curtains need to be stretched they wouldn't be in my house!)
Should I list them on Kijiji or donate somewhere - historical society or heritage village?
