I just pillowcased a small quilt. I have only done that once before, but after doing two bindings last week, I just didn't feel like sitting down and hand-stitching a binding. A few weeks ago, I did what you're doing and turned the backing over onto the front and stitched it down. It wasn't perfect, but I didn't care. I think whatever works for you, do it.
My mom gives me grief every time I give away a quilt. I get the "when am I going to get one" speech. It gets old. She is an artist and can turn out a painting in a few hours, so I have five or six of her oils in my house. She just doesn't get that making a quilt is MUCH more time consuming and expensive! I make mostly baby quilts and doll quilts because I just don't make the time to commit to larger projects. Not only that, she is very critical of my color choices (since she is a professional artist.) It drives me up a tree... which is probably why she doesn't own one of my quilts.
I sympathize with you. I really do.
