I totally agree, you are not doing anything wrong!! If you were, I'd be also, lol, and I know I'm doing mine just fine!! LOLOL
I ALWAYS stitch to the back first. I am also one who machine stitches the entire binding, due to physical problems I just can't manage hand sewing more than a very small amount.
Carry on! Have fun! Ignore anyone who tries to tell you there is only ONE right way!
Hugs and smiles!
