Sewing is a therapeutic hobby, although dedicated crafters might be inclined to disagree at times. An overlocker sewing machine takes one step out of any project by helping trim excess fabric as seams are sewn.
This handy trait increases the quality of the item being sewn by tidying up for the crafter. Additionally, this provides a consistent cut that increases how professionally done the piece looks. A quality overlocker not only helps save time, but complements the skills of a dedicated crafter.
