Check a post or two about 2 weeks back when I tried a gate-fold version and an off-set/overlap type fold. Then a few days ago I tried a variation where the front was folded-in and then I used two fabric brads that look like buttons. This was done on an anniversary card and there's a photo of it posted on the top right side of my blog page.
In the past 2 days, I've tried a decorative cut edge (vertical right side) with a fun way to embellish the edging and a scalloped cut edge (horizontal bottom edge) for Easter theme cards. I'll post photos showing cards closed and open.
