here's a link to frame instructions...
Instructions for the Inspira Frame attached
The machine and frame are usually sold together(used)...you might be more able to sell it if you ask a local quilt shop to sell it on consignment for you. As for selling yourself..people hardly ever sell the frames with the bars if it's going to be shipped, as it's cheaper for people to buy the conduit locally than pay for the shipping.Also.. you'd have to take it apart to ship it, or deal with showings locally..since neither you or your sister sew or quilt, the chances that you could answer questions from sellers is very low, or fix a minor problem, (like tension) that could put a buyer off from selling it. I'd start asking local quilt shops.
