Enlarging pattern
I'm hoping someone can help me. I have found a quilt pattern I want to make that is about 57 inches square but I need it to be 90 inches square to fit my bed. It has one large central motif of approximately 18.5 inches which is surrounded by 6 borders each containing different smaller motifs. To get the required finished size I am thinking I will repeat 4 of the borders. My quandary is how I go about calculating the extra fabric I am going to need for each of the extra borders and their motifs. How do I go about this?
