I stitched the border squares together, alternating a white block with a purple block and with one facing up and one down. I decided to keep the white edge toward the quilt centre, so I added a white border first, then the pieced border, then the purple border.
The picture was taken after I had pin-basted my quilt, and had stitched "in the ditch" around the basic shapes. I then added a scrappy binding, made from left-over 2 1/2 inch strips. Now on to the remaining quilting.
