Cut an 11" by 11" square of fabric. Note: If you are using a sheer overlay as pictured here, layer the fabrics and work them as one fabric. Baste the layers together if it makes it easier for you to work with.
Stitch lace to the edge of one of the fabric squares, stitching 1/2" from the edge. (Place the lace to the inside of the square so that the edge will be in the seam allowance)
