Abstract: A sewing data processing apparatus which may be used to attach an IC tag to a work cloth without impairing a design of the work cloth. The processing apparatus may acquire an IC tag area on the basis of a size and shape of the IC tag and subsequently may determine whether the IC tag area can be included in an applique pattern area which is determined on the basis of applique pattern data. If the IC tag area can be included in the applique pattern area, positions of the applique pattern area and the IC tag area may be set in such a manner that the IC tag area is positioned in the applique pattern area.
