Hi there. I'm new to the forums and hope this is in the correct location.
I am making a box for my wife's calligraphy stuff for her birthday and am attempting to do something like the included picture. I know how to make a simple mitered spline joint but I am unsure of how to go about making ones like those in this picture. Specifically how can I make the vertical maple pieces that join the two splines in each of the spline pairs. I would greatly appreciate any ideas on how to do it, or direction to any tutorials/videos of someone making something similar. Thanks for your time and assistance!
