I just made a phone holder--so simple and all the kids getting one. I use a stiff Pellon, about 10x5", cover with fabric, put 2 pockets on front (one for phone, one for earbuds, keys or sunglasses to tuck in) and cut a hole (I use oval) above the back/phone pocket--they can either hang from the door knob with stuff they need as they head out, or hang on the phone charger plug-in while charging. I made 4 in one hour out of scraps.
