I have just bought a 9 degrees ruler and pattern for the table runner but cannot make sense of it. Can anyone help by showing how the cuts are made. I have sewed all my eight fabrics together in the necessary strip sizes but cannot understand how to cut them. Do I cut both sides of ruler to get my wedges or how when I turn it round do I get the second set. I probably am very stupid to be asking this question but would love to master this project. Many thanks in advance.
