Unit Four is about those little things that everyone else assumes you either already know, or can muddle through without assistance. We here at Sewing Prose know that it is these very little things that make the difference between enjoying sewing while creating good-looking garments, and just throwing things together and having the finished project look like it. Facings, pockets, and flat-fell seams build up that solid base of skill. These skills will be relied on in future lessons as the backbone of construction.
