I have a Harrisville Design warping board for sale for $50 (retail is $130).
It holds a full 12 yard warp and can accommodate two crosses. It can be easily disassembled for more convenient storage when not in use. The board is in good condition and has been finished (the kits when bought new come unfinished). It has two holes drilled in the frame that I used for hanging on the wall and two pegs had a few puppy teething marks that I sanded off so they are lighter.
I live in the Pittsburgh, PA area for a local sale. I will also be at Maryland Sheep & Wool next week on Saturday and 1/2 of Sunday and can meet up at the festival to deliver if anyone is interested.
I have not priced shipping, but given how heavy the board is, it would likely be around $25-30. If you are interested in shipping, pm me and I can investigate.
