There's a site called
colourlovers.com where you can create your own color palettes and patterns using those palettes. The patterns are premade, but you can manipulate which colors you want in which design. There's a lot of cute patterns. AND you can buy the fabric!!! No need to worry about licensing if you happen to want fabric with blue owls for example.
Psych: There are some wonderful colourlovers that make pattern templates, so you can make your own if can figure out how.
