Gorgeous fabric! Yep, I have done that also.
Right now I'm lovin the tumbler pattern. How much of that solid purple did you buy? That's a good separator fabric. Summer Porch by Quilt in a Day would be very pretty using that solid purple for the sashing and it would showcase the pretty prints.

Your stripe fabric would be gorgeous cut on a diagonal for the binding - also easier to match up seams.
