So the original post was made in 2011 and you are still trying to talk INGEMK into our out of making the quilt? LOL
wesing ~ The Trimplates must still be available. I went to a talk at a local quilt guild give by Wendy Mathson, who it seemed had designed the Trimplates. If you took her two-day workshop, you could buy the Trimplates. It was just last month. I don't think she sells them online though.
I think I would use paper piecing ... and hope to do that someday ...
