Setup that takes less time
Threading and winding the bobbin take up most of the time before you start sewing. The automatic needle threader on the Singer 3221 guides the thread through the eye of the needle, and automatic winding fills the bobbin without you watching it. Stitch length and width are adjustable, so the same stitch works for a fine or a stronger seam. The vertical shuttle is the type of bobbin system the machine uses.
