Please learn how to make a separate binding for your quilt and thereby improve and increase your skill level.
This back-turned-to-front finishing of quilts is something we saw a lot of in the 60s, 70s and very early 80s until the ressurgence of quilting began in the late 1970's. It was, (and still is) in the greater quilting world, thought of as a lesser/easier/(lazier?) way of doing the finishing. Of course, like anything, there is a time and a place for it, and I've even done it myself.
But you will feel so accomplished if/when you learn to do a finished binding! Good directions are available in the backs of most uilting magazines. Enjoy!
