The continuous lap placket can be used on sleeves, at the back of a neckline, or below a back button opening especially on children’s wear. The placket binding may be cut on the straight grain or bias from the same fabric as the garment being made.
Well, the Continuous Lap Placket may just be your next best friend! So called because it laps around in one continuous line, this super useful bit of sewing know-how is fabulous for finishing slit edges, while also giving you a place to anchor hooks and eyes or other small closures.
A lapped seam is the seam created when one piece of fabric is laid upon another piece of fabric with an overlap. The fabrics are both right sides up, and by overlapping the fabric, you end up with two layers of fabric instead of up to four when using other types of seams.
a seam in which the edges overlap especially : a seam in leather or cloth made by extending a cut or folded edge over a cut edge to the width of the seam allowance and stitching in place.
The simplest way of finishing a slit is with a facing. The next simplest is probably to have a curved bottom to the opening and cover the edge with bias binding. Openings where one side of the opening lies over the other are called plackets, which this post is about. Zippers became available about a century ago.
any opening in a piece of play equipment that is totally enclosed by boundaries on all sides so that the perimeter of the opening is continuous.”
