Interesting -- evidently that specific item isn't available for sale in U.S. due to patent issues. Just something I've read, no solid proof -- but it's not listed at bonash.com, and I don't even find any on eBay (not that a patent issue would stop an eBay seller LOL). I'll have to try one of the "similar products."
Interesting. Not surprising though. I attended sewing conferences for several years and met the person behind the product. She made it at home, in her living room apparently. I don't know her personally however, and this is 3rd hand info gleaned about 3years ago, but some retailers had supply issues with the company.

If you're interested, I do have a contact that used to sell these at sewing shows. I'll email her and see if she has any to sell.
