I’ve used wooden stands on shelves where I’d set up cards though I’ve gone to other things on my shelves lately. I ordered from Etsy and had some custom made for the specific shelf space I had. But that was just for a handful of cards. I displayed autographed baseballs and bobbleheads in the same grouping based on favorite players.
I’d say it depends on how many cards you want to display. I saw all kinds of options when I was looking online to decide how I wanted to set up my displays. I bet some people on here have some great suggestions based on cool stuff they’ve done.
