Shadow box design question

would biscuits work? i do have a biscuit joiner that I’ve never used

Are you going to use hinges, or take the picture lid off? Or are you asking how to attach a picture frame as a front for the shelves?

If you use glass as the front, you’ll want to allow for the possibility that it may get broken and will need to be replaced. If you use dowels or biscuits with glue this won’t be possible. I used pocket-holes and painted the white plastic hole plugs to closely match the color of the wood in this shadow box. If you look at the first picture in “zoom” you can almost make them out.
