All of the baseboards in our house were plain and short. Instead of pulling them out and replacing them with hundreds of dollars worth of moulding, we added foam casing right on top. Looks just like the real thing!
Several years before my daughter was even born, I made a trade with my neighbor at a garage sale for his old entertainment center with the intent of converting it into a changing table system for a future child. Years later, that's exactly what I did. It has been a great addition to her nursery and has taught me to always think outside the box and even down the road a little too.
