John Flynn's template sale, per newsletter that I just received, some of his templates also have registration marks to match up those curved pieces. For those of you who have questions about his quilt frame system there is also a link on his main page to a video you can watch demonstrating his frame.

FREE SHIPPING ON TEMPLATES– I worry that there are quilters out there
who haven’t tried our acrylic templates even though they are
inexpensive, accurate and have engineered corners (professionally engineered,
not just “faked” like some other template vendors), just because of
the shipping. Here is a way to try our templates or to add to your
collection. Buy any two templates and we will pay the shipping. It
could be two $5 templates or two of the more expensive ones; you choose.
Or buy lots and lots and let us ship them to you for no shipping. The
computer will charge you shipping, us humans will adjust it off, so
don’t worry. Continental U. S. retail orders only, please, and this
special ends September 19, 2007. http://www.flynnquilt.com

Thanks for the heads up on the template sale! I just bought the wheel of mystery templates, been wanting to try that set for a while! :D :D
