It's something he'd appreciate. I think Velcro would trap hair , and buttons or snaps wouldn't hold up in the wash over time. And I don't think
theyd be comfy. My son isn't a teenager who has never liked a top sheet but he loves a fleece blanket or a quilt. If he asks for one, I'll make it simple and durable and plenty big enough to
wrap up in . Wash when smelly-- happens even with daily showers. Ahem. Heck I wash my own quilt about every three weeks for that reason!
