Just an FYI on using rulers for quilting...you will need the bed of your sewing machine to be level with your table or have an acrylic "table" to create a larger flat area to stabilize your ruler. I quilt on a longarm and when I use rulers, I have to attach an acrylic table to my machine. Rulers are fun, especially when you figure out how much pressure you need to hold the ruler steady while you quilt around it.
