I have never heard of Olive Rose fabrics, so I googled them to see---very lovely indeed!!
Since your fabrics are mostly large print you could do a quilt that has some large blocks to showcase their design.
My first suggestion is to look here---these free patterns are all designed by Valori Wells and made with her fabrics!

And here are a few more of hers

Another suggestion is the Big Block Beauty quilt--

Or you could do an attic windows pattern--

I hope these ideas get your juices flowing and can maybe inspire you in some way.
And be sure to post a pic of your quilt when you are finished. I would love to see what you make with these beautiful fabrics!
