Like Maurice, I've had the little Ryobi biscuit joiner for years and use it on occasions like this. Like it's big brothers it has 3 biscuit sizes. It especially works well for picture frames where you don't want the see the end of a spline joint. And if the material is thick enough I use 2 biscuits vertically. I've never had one of these joints fail, even on a large lazy susan with a marble inlay.
