Doors can be so much more. If you've ever lived with a hollow core door (like most of us) you know what I'm talking about. Even if you can't have something like this secret library door, by Peter Pennoyer Architects, there are other ways to do it up. Here is some inspiration:

1. Cover Them: With starch and water, you can "wallpaper" fabric to any surface. When you're sick of it, simply pull it off. That's your cue to get giddy from all the possibilities.

2. Camouflage Them: Painting the door, trim and wall the same color cleverly masks a not-so-pretty door. Spice it up with an 80s inspired mural and there is now "art" where there was previously only "door."

3. Wallpaper Them: With some leftover wallpaper, BOOM. Mini accent wall.

4. Paint Them: This is a quick no-brainer. Choose one solid color, or an inspired pattern, and go to town on that hollow core door.

5: Chalk Them Up: Okay, this is really the same as painting. But it's especially entertaining for such notes as "I live with stupid."

6. Accessorize Them: One ceiling medallion and some hardware later, you have a formerly blah door that looks super custom and expensive.

7. Stud Them: Apply brass nail heads in any design you can dream up and do. But promise me that you'll buy them in strips vs. individual nails. Otherwise, you won't have time to brag about your finished project.

8: Slide Them: Attaching existing doors with sliding barn hardware saves room and creates an new architectural detail. Also perfect for farmer and wife role play in the evening.

9. Upholster Them: This might require a little more time and energy if you do it on your own, but a padded entryway is the shizznit. Let's take a moment just to admire that zebra stripe door, shall we?

10. Fold Them: And the pièce de résistance: I love this set of doors most. A leap of faith and some creative finagling is required here, but I believe in you.
