Jen of IHeart Organizing used a Home Depot stair tread cap and riser kit to transform the look of her staircase. (New wainscoting and paint, helped, too, of course.) See the staircase makeover reveal (Entry Step Basement Stairs)
I LOVE this idea for Emilyn's room. To have a "playhouse" all the time that can grow with her - from kitchen set to a reading nook and all things in between. Definitely a look into for her big girl room!
