I have been making my own "print" vinyl by taking a pattern cut out of one color of vinyl and layering it over a contrasting color vinyl. There are several posts on my blog that offer svgs you can use to do this yourself. Find some of those here:
Here are a few more you can use in much the same way:
Modified Houndstooth svg here
Swirl Pattern svg here
Complex damask svg here. (For those of you with lots of patience who like to weed!!)
A damask element here
Hope you find a use for one or two of them!! Thanks for looking!
