The apparatus comprises a sewing mechanism, an automatic thread supply device, a key input unit, a memory, a selector and a display. The sewing mechanism has a sewing section which includes a needle and a looper driven in accordance with a rotation of a main shaft. The automatic thread supply device forcibly carries a needle thread and a looper thread to the sewing section. The key input unit sets lengths per stitch of the needle thread and the looper thread which are to be supplied by the automatic thread supply device to the sewing section. The memory stores a plurality of stitch patterns in correspondence with combinations of the lengths of the threads to be supplied per stitch. The selector selects one of the stitch patterns corresponding to the combination set by the key input unit. The display displays in graphics the stitch pattern selected by the selector.
