Tiny pleat

The bottom of the sleeve closest to the cuff is split and hemmed, and there's a little pleat at the bottom where it goes into the cuff. I will add a tiny bit of the ultra thin velcro to secure the cuff and add a bead button to the outside (or maybe a pair for "cuff links"?), since if I simply sew the cuff closed, I'll have to remove his hands every time he wants to change his shirt!
