Lately I've been thinking that I would like to try the twister pattern and have checked out the price of the templates on line. I just came across your directions and they sound wonderful. I'm going to see if I can get the book you mentioned and try making a table runner. I like the idea of cutting using a ruler as I do not trust myself trying to cut around template plastic. Thanks for your great information!
P.S. I just found the pdf for the patch that you posted. Thank you so much.
