5. PLEATED SKIRTS AND DRESSES
To sew a pleat, begin by marking your fabric. Precise marking will help you get crisp, even pleats. For each pleat, you’ll have three marks: two fold lines and a placement line. When sewing a box pleat, I find it’s easiest to make my marks on the wrong side of the fabric.
Working on the wrong side of your fabric, fold one of the fold lines in toward the placement line and pin in place. Repeat with the other fold line.
Machine baste across the top of the pleat to secure. Press. Depending on the construction of your garment, you can either leave the pleat as is, or topstitch the pleat.
