Lol, I must have been in the cloth diaper world too long, or I haven't switched acronyms well enough. I clicked on this thinking, "Pressing DWR (durable water repellent?) Is that how you set it? Can't remember, better see what everyone is saying." Weeeellll this was a surprise! I don't have amy experience with this kind of DWR, but I did see a flimsy for sale in a local thriftstore (it was $150.00, so not actually very thrifty.) It had puckers in the pointy ends of a few of the footballs, and I was wondering how that happened.
The tag said it was vintage, and the fabric looked like it may have been preWWII. I'll post the pix one of these days and we can discuss it.
