Thanks Jeanne S. I felt dumb asking this question but I found patterns that said to use the 60 degree equilateral triangle ruler and some that said to use a 60 degree ruler. I do have a 60 degree ruler that goes to 8" and most patterns say to use one that goes to 12". I am sure that the ruler you would use would depend on the size of the border print.
Thanks the responses. BrendaK
