Eric - the "Loft"
...
I have read that one can use a spreadsheet to put the Offsets into and graph the lines, then transfer it into a CAD program and print out the patterns. I don't have a CAD program....

If you wanted to go that route Eric, I'd be glad to assist.  If you wanted to send me a spreadsheet, I can plot it all out for you and send you printable drawings.

This "lofting" is fascinating to me and just went on my list of things to learn about.  I don't quite grasp it fully from your's and Paul's explanations but I think I get the gist.
