Marta Alto shows how to use a serger sewing machine to stitch a seam, trim the fabric, and overcast the edge in one step. Other lessons include tension adjustment, threading, gathering,
rolled edges, and flatlocking, and tricky details are explained for collars, cuffs, hems, bindings, children's clothing, lingerie and swimwear, and home
decorating projects. Real people model the finished projects throughout the video.
