If you look at Jinny Beyer's Facebook entries you will see many uses of her fabric. I have been working with her border prints. there usually is a wider section and a narrow section separated by a black line.My method is to decide how I want to use the fabric...border with sashing, or border and sashing; then separate the two by cutting 1/4 inch of the black for each design. I lay out the fabric so the lines are running up the mat away from me, use in 24 inch ruler to measure 1/4 inch , I then cut up to the top of the mat. I do each line before moving the fabric to do the next section. It work for me. JB Studio has a wonderful "Sock Quilt" design with a center design of 9 patch sections with brilliant palette colors separated by sashing that helps you get used to Border Print usage. She also has many tutorials on her site. Hope this gives you some ideas.
