• acquiring a bobbin thread remaining amount;
• setting one of the objects as a determination target in accordance with the sewing order;
• determining whether or not the object of the determination target is sewable, based on a difference between the required bobbin thread amount of the object of the determination target according to the pattern data and the bobbin thread remaining amount, and
• excluding the object of the determination target from sewing targets when the object of the determination target is determined not to be sewable, and set another object in the next sewing order as the object of the determination target without warning for a shortage of the bobbin thread.

A sewing machine, comprising:

• a memory storing a program;
• and
• a processor configured to execute the program to:
• acquire pattern data in which information on an object corresponding to a unit from a sewing start point to a ravel preventing point or a thread trimming point and information related to a required bobbin thread amount required for sewing the object are associated with each other and registered;
• acquire a bobbin thread remaining amount;
• determine whether or not the object is sewable, based on a difference between the required bobbin thread amount of the object according to the pattern data and the bobbin thread remaining amount;
• and
• decide whether or not the object is set as a sewing target based on a determination result of the determination unit;
• and
• wherein a color layer formed of the objects of the same color and information on the objects forming the color layer are associated with each other and registered in the pattern data,
• wherein the processor is configured to execute the program to:
• select any of the color layer as a determination target, and in the selected color layer, determines on an object basis whether or not an object is sewable, and
