I've been making these wallets, and I have found that by using my 1/4 inch quilting stitch on my machine that if I keep it on that stitch and line it up with the edge of the binding with the middle marking line on my presser foot. (when I turn it to the other side) it almost comes out perfect every time. LOVE IT. Follow the stitch line that you sewed the binding on other side. I don't know if I am making myself clear or not. On my quilts I have always hand stitched them
