Yeah. get to a Fabric store get a pattern YOU like that matches the paint job of the van. Then, go to the hardware store. Get a couple of Springs. Use those for curtain rods. Cut, then sew the fabric with a loop at each end, FINISHED height the same as the window. Two panels per window. That's how WE did it.
If you have a van to put curtains in then you are blessed and should do whatever is comfortable to you. I envy you.
My curtains kept falling down because I did them in a hurry and I only had sticky-backed velcro. Which, I must add, doesn't work. At all. Especially when the inside of your car gets condensation-y. Yes. */random*
