Cinderella coveted

a tub tray. Therefore, she fashioned one.
You can do it, too.
Measure the width of your bath tub.
Salvage. She found a plank of discarded fencing, aged is better. Cut to desired length. Grab a belt sander (her favourite accessory) and sand off the slivers and lichen.
Apply one or two coats of White chalk paint ( Annie Sloan https://www.anniesloan.com).
Stencil a royal touch (she will find her crown).
Sand again.
Wax. (Annie Sloan Clear Chalkpaint Wax.)
