An apparatus for processing embroidery data needed to control a sewing machine to form an embroidery pattern on a work sheet, the apparatus including an outline-data memory which stores original-outline data representing at least one original outline of an original embroidery pattern, the original outline including a plurality of segments, a reference-vector memory which stores data indicative of a reference vector specifying a reference direction and a reference length, and a shadow-pattern embroidery-data producing device for producing, based on the original-outline data and the reference vector, shadow-pattern embroidery data needed to control the sewing machine to form stitches of at least one shadow embroidery pattern which is contiguous with the original embroidery pattern and whose outline is defined by at least one of the segments of the original outline and at least one of two straight width-defining segments which extend in the reference direction from opposite two ends of the one segment, respectively, and each of which has the reference length defining a width of the shadow embroidery pattern in the reference direction.
