I know I am in good hands here on this board. I need help figuring out how much fabric I need. I have a quilt top that is 76 inches long, 62 inches wide. I want to add fabric to the sides and bottom with a 16 inch measurement. I want to make it like this: A brown 6 inch stripe, then a 4 inch white stripe and finish with a 6 inch brown stripe. How much fabric of each do I need? Please tell me how to figure this. Any question that I have not covered, let me know. Thanks everyone.
