# 2 - Brother EF4-N21 Twin Needle Overlock:

The Brother EF4-N21 twin needle overlock is used to serge over the edge of one to two pieces of cloth for edging, hemming, or seaming. The machine has a small blade that cuts the edging before the machine loops are fed by multiple thread cones rather than a bobbin.

This machine is set for “faux” safety stitch, with two needles, and works well on woven materials. We only keep black and white thread on hand, so you will want to bring your own matching thread cone(s).
