Topic tags/keywords: frame spline

I’m working on a picture frame and have made a table saw jig for the corner splines. Where I’m confused is about what I’m reading about the wood used as the spline (or whatever you call the triangular insert). Specifically the way the wood is cut.

I would think I should cut it so the grain of the triangle goes long ways so the grain direction stretches between the two pieces of the picture frame. Is this right?

Sounds like you got it!

The grain should run orthogonal (at a right angle) to the miter joint. Since this exposes the end grain of the spline along the side of the frame, it typically will be darker than the surrounding wood when a finish is applied. Steps can be taken if you want the spline to “disappear”, otherwise consider it a design element.
