Creating your own background patterns for design projects is quite laborious. And making a background pattern for one-off use may be impractical, considering the time it takes to make a really good one.

If want to find a ton of high-quality tiling/repeating background patterns to use in your designs, head over to Subtle Patterns.

I should also highlight that the 382 patterns and textures — and more are added regularly — on Subtle Patterns are free.
