I’ve searched the net, but it appears The Potholder Lady has gone into cyber-hibernation and now only be found in archives. Scroll down the page for a peep at her original Pinwheel Placemat, but no pattern. Sorry! 🙁
If anybody stumbles across TPL again, please let me know.
ETA March 30 2008: Even webarchive no longer has The PotHolder Lady’s site. Which is a great pity. She had some lovely patterns.
