Decorating the walls of your home office doesn't have to be a big investment on time or money. We like all the tech alternatives there are available now as opposed to dropping a lot of money on an expensive painting or wallpaper. Thanks to digital printing and wall decals, you can add a lot of personality to your home office walls with these designer decals and digital printing services.

Here are some of our favorite designed and customizable digital printing services to consider.

Spacetime Wall Decals: You get four different decals in this package by Poketo. The Spacetime design is fun and whimsical, you can decorate one room with all four decals, or have a bit in each room. For people who want to add some fun to their rooms in a simple way, these decals are easy to peel and stick. They are also restickable so you can stick and re-stick whenever you want.

Shanna Murray Illustrated Decals: Another set of simple decals we like is by illustrator Shanna Murray. Her decals are perfect to stick inside a home office and you can often use them to compliment your personal decorative items like photos or prints. Shanna Murray's decals add instant cheer to the room.

Plywerk: Plywerk lets you display photography or artwork and skip the expensive framing process by mounting your image on sustainable, harvested wood. They make the process super easy for the user, simply uploading your image, choose the size of the plywerk you want and purchase.

Printed Space: Here you can create wallpaper that truly fits your home décor. Printed Space tailors each decal to fit your room's dimensions perfectly.

Blik Wall Graphics: Blik Wall Graphics gives you the option to shop through their products or customize your own wallpaper. They have a great selection to choose or you can submit your own "wallscape" to be made.
