An apparatus includes a processor and a memory configured to store computer-readable instructions that instruct the apparatus to perform the steps of acquiring first pattern data representing stitches that form a first pattern and second pattern data representing stitches that form a second pattern, the first pattern and the second pattern being two patterns to be sewn by embroidery in mutually adjacent positions, generating, in a case where the two patterns are to be sewn on a sewing object that is formed of a soluble material, connecting data representing a connecting stitch based on the first pattern data and the second pattern data, the and generating, from the acquired first pattern data, the acquired second pattern data and the generated connecting data, embroidery data to sew the two patterns and the connecting stitch.
