Your choice!
For me, preferably some of the backing fabric is used in the front.
Or at the least, something that coordinates with the front.
That might be as simple as go-with fabric colours/prints.
Or possibly a print that goes with the theme of the front.
But that's my personal preference. Do what works best for you.
