I was looking online and some of those acrylic stands for flyers and business cards run upwards of $500! I've seen some cheaper $5ish ones, but the shipping alone was more than the product. I just needed one to display, so I figured i'd just make it for free out of wood i had in the back.
Surprisingly, I got a lot of compliments on it. Since I already put out the better one I made (and of course no pics), I whipped up this one up out of cardboard in about 15 minutes for a tutorial. It looks like crap, but bear with me. It looks way better once you throw some love into it, promise.

Excuse the rough edges, I couldn't find my ruler and did this one fast just for a tut. the top has cutaways so it's easier to grab the flyer.
Tutorial:

my measurements. after you cut it out on cardboard you can tweak it to how you like it. (For wood, run it through a planer so it's all the same thickness, and cut all those pieces out. Sand out the rough parts)

cut it out and score the creases

beautify, hot glue together, and fill up. (For wood, wood glue together, then use small nails to fasten it. Sand, then paint if desired)
i added a card holder last minute. it's basically card sized, with 2 side flaps and a bottom flap.
it also works fine if you don't use the side flaps, and add one fin in the back.
