How could I create a wall vinyl?

sponges, and thick cardboard tubes, and light brown paint

This company will print your own design for you.

I had a vinyl wall mural installed in a house once, and it completely transformed the look of the room. But, if you do not want a giant photo on your wall, see if you can buy the unprinted mural material and just put up a blank wall, suitable to be your ongoing canvas.

Getting a good installation is a bit tricky, requires sanding the wall several times to get it very smooth, then getting the large sheet of vinyl up without wrinkles. I hired a pro and he was worth every dime. Don’t remember the cost, but it was not bad at all.

Do you want to install a vinyl or paint your own? I’m thinking painting would be easier than applying a vinyl.

tyrantxseries was on spot with the tubes, I would make them various sizes. The splatter with a thick bristled brush or stand back and use your finger to flick it. A spritz bottle held close would work too. The sponge for splotchy accents.

Thin your paint down to a runny consistency.

Check out blik.

We ordered one of their designs for our office at work and it made the room look awesome.

I thought the design was great. But do you want it huge – like, that design would dominate a whole wall – or repeated? I know you can do this with paint (at least, I could). If you don’t feel confident about that, go to the nearest art school and hire a student whose work includes these kinds of marks.
Blik’s designs are wonderful. I couldn’t find their custom capability on their site though.

You can design your own and have your local printing shop or signage shop print it for you.

@syz where does it say I can do custom designs?

My apologies, cage, I linked to one of my favorite sites, but not one that does custom designs. These, however, do:
