It will never match the beauty of a dovetail or the strength of a mortise-and-tenon, but for speed, accuracy, and ease of use, it’s hard to beat the biscuit joint.

Biscuit joints can be used on all wood products and on combinations of different products in one piece. For example, they are a great way to join a plywood carcase and attach an assembled face frame. They also help keep things aligned when gluing solid-wood edging to plywood or assembling solid boards into a wide panel. Tom Begal lays out the basics of biscuit joinery for beginners.
