On my mantel project I am planning to do mitered returns on the top (and a lower shelf) to hide the end grain. Drawing below. Given the top is under a foot wide, Can I just glue on the return using a domino or two? Or do I need to just glue the miter end and then use a dovetail key or the like to hold the long part of the return so it can move independently of the rest of the top. Wood is cherry.

The safe approach would be to glue it for the front few inches, and use some sliding joint at the rear. Instead of sliding dovetail, I’d use construction like a breadboard end: longish tenon with crosspins. The pins go through oval holes in the tenons.

glue the front corner and stick a 6 penny finish nail in the back. nail set and a dab of putty. simple and effective. it will allow plenty of movement over 10 inches.

+1 for Adam's recommendation, simple and very effective.
