I have the pounce and yes it was expensive vbg, and I don't have great success with the pounce, I like your freezer paper idea better, I don't think my old printer would stand up to printing straight onto freezer paper but I could stack about three pages and sew the design without thread, at least I would know the design after doing this a number of times.
If you know of anyone heading this was a roll or two of freezer paper would be apperciated
