Depends on how "good" you want it to be.
There is "half fast" - and then there is "done correctly" - even if it takes a bit more doing to get there.
I have started to baste the three layers of my quilts together before I put the binding on - so then I only need to worry about keeping the binding and quilt sandwich lined up. I also had that "folded under" - "missed" situation - and even though it does take me a loooong time to finish a quilt - I have yet to redo one that I did finish!
Not everyone is as persnickety as I am - you know your "tolerance" of when something is needs correcting or it is "good enough
