For most people, picking up the right curtains is an afterthought or does not really matter. And most of the time, keeping curtains in the room is the rule. Don’t.
Having all rooms in the house wear the same curtain style is not a rule, nor necessary. In fact, each room can have its own curtain style depending on the concept. If you want a child themed curtain in your kid’s room while giving your living a totally different theme, go ahead.
Be aware that changing up curtains from room to room is totally fantastic as long as you consider the general theme of each one.
After all, you don’t want luxurious and bold window coverings in your child’s room.
