It seems like every time I want to make a new quilt I have to buy another ruler ? This time it is a Tri -Rec Tool. For making triangle. It looks like the triangles are more spiky then normal triangles. ANybody have the answer? I am hoping to make a Civil War quilt in the Fons and Potter magazine, called Evening Start. Has anybody made this one before? I am getting really tired of buying new rulers. Maybe I just don't have enough tools yet.
