Pre-wash both front and back ca few times before basting and you should be fine. Flannel doesn't look brand new after washing though, but if it's just for you then no problem. Also, I have heard not to use sheets to back quilts because they are a different thread count than quilting/decent cotton fabric and over time the front a back will shrink and wear differently.
I have washed all the fabric already so the shrinking should be out. This is a quilt for me and hubby on our bed so it won't get lots of use - it's more to look pretty - so I think that using a sheet should be okay.
Thanks to everyone for their advice.
