Thanks Don. I also plan to stick to the traditional drawer design for these.
The drawer dividers have bridle joints which are hidden, a great chance to practice that won't be seen. I've cut lots of dovetails but not so many tenons by hand, so I decided to do some practice.
Nice white wood--no blue tape needed, but I did trace the gaged lines with a 0.3 mm pencil.
Start on a diagonal, working to saw right up to the line.

The first one was not too hot...
But did better on later corners. Discovered my new favorite chisel.
In the end, the practice piece will get turned into a photo frame...
And the divider pieces squared, cut to length and ready to mark:
