I've just cut out the quilt top for my first non-quilting kit quilt. The only part I haven't done is cut out the rectangles for the border. The directions need 40 3 1/4 by 5 1/2 squares. I just don't know what material to use. I have a yellow, but I don't know if it should be all yellow? I still have enough of the other fabrics left to cut out some with those. What do you think?
