Out with the old
If you want a clean slate to create a new bedroom you'll both love, you need to get rid of stuff you don't love. You might still have your coffee table from college, and she might still have a dresser from high school, but neither of them will likely fit your vision for a stylish new bedroom. You've got to get rid of the old stuff to make room for the new!
Getting rid of them doesn't always mean throwing them away. Sometimes your old furniture is still functional, and someone else could still get some use out of it. If you want some money to put towards your new bedroom, selling your old furniture online is an easy way to make some quick cash. If you don't need the money, many nonprofit organizations such as Goodwill, Salvation Army, and other local charities accept donations. There are a few that will even pick up the furniture!
Before you start selling or donating your furniture and decor, make sure you're both in agreement on what stays and what goes. Some older items might fit your vision for the new room after a quick coat of paint, so be sure to keep an open mind.
