Handheld sewing machines are useful for emergency mending, remote repairing, and minute tasks. Moreover, they are great for cultivating sewing hobbies in young kids. However, heavy and speedy tasks can not be expected from these machines. For example, I could easily sew the seams of my curtain by using my Singer Stitch Quick + in handheld mode. However, without such a handheld machine, I would have to first remove the curtains from the curtain rod and then put them back again after sewing them.
