When measuring for borders on your quilt, begin by spreading your quilt out on your work surface making sure that it is laying flat but not pulled tight. With a tape measure, measure from one edge to the opposite edge across the length of the quilt. You should measure along two or three different seam lines and cut the border material to correspond with your longest measurement.If you would like a two-inch wide finished border then you should cut your border material two-and-a-half inches wide. Once this border has been sewn onto the two longest sides of the quilt and ironed, repeat the above process to measure the width of the quilt with the new borders attached. Cut the borders for the remaining two sides of the quilt, sew on, and iron.
