I was lucky enough to get a used warping mill at Christmas so I don’t need my nice wall-hung warping board any more. I have had it a couple of years so I can’t locate the eBay vendor but they made it themselves. It has eye hooks at the top right corners so it can be hung on hooks or nails, and it has wing nuts that unscrew at the corners so the four sides can be separated. It could probably be shipped but it would be easier to transfer it by hand. Asking $75. I live in Baltimore. Thanks!
