On baby quilts, patterns often call for the binding to be 2 different widths & I like that look. As long as it's a relatively consistent width on the front on all 4 sides, I'd call it a day. And then maybe make some little whole cloth quilts so you can practice binding -- no need to use LQS fabric, just pick something up on clearance at JAF or HL and donate to charity or give to a sweet little one (family or friends). The only reason I'd re-do it is to enter a show or it was wavy or not securely attached. No one started out making perfect quilts (and for that matter, even the most brilliant, award-winning quilts aren't perfect) & I'm of the opinion that the world will go on even if I send a flawed quilt out into it.
