Great advice from the others...I especially love dcamarote and her "man on a galloping horse" analogy...
..Though I must be honest and say I have been known to take things out that no one would consider re-doing..my dh has joked with me that he thinks I like taking things out more than making them!
I always cut my binding strip a tad larger, I can always cut more off, can't add it back. I also leave my backing fabric a little larger when I use it as the binding...
