To use this Calico Critters Bedroom & Vanity Set, first place the bed, dressing table, shelf, and table in your Calico Critters house where you like. Arrange the mattress, cover, and pillow on the bed for a cozy look. You can put the small accessories like the hair dryer, brush, and cosmetic bottles on the dressing table. When playing, move the swiveling mirror on the dressing table to create different scenes. You can also pull out the drawer to store small pretend items. As for maintenance, keep the set away from sharp objects to avoid scratches. Wipe it with a soft, dry cloth regularly to keep it clean. If you want to combine it with other sets like the Piano & Desk Set, just make sure they fit well in your play area. And remember, the houses, furniture, and figures are sold separately, so you can mix and match as you please.
