Here's a link with lots of ideas:
Liz...we had left over vinyl and my husband covered the walls and shelves of the bathroom that also had the floor. It looks great!
Shelf bottoms, make wall shelves, hang on to some in case there are issues with the floor.
Install it on a ceiling. It's beautiful on a ceiling and it draws your eye up. I see this kind of thing a lot on the Home and Garden channel I watch.
Make some DIY wood signs! They're so popular now.
