How often do you edit a poem?

[billy]

I have to be honest and say
I've written very little poetry lately.
most is old stuff. I tend to shut them
away and after a long forgetful break
uncover them, dust them off, and redress them.
I find it amazing how drab some of them look when
i pull them out into the newness of a fresh day.
some of them i still love as they are but even in
those i can see a need to spring clean. So I do
tend to do lots of edits to my stuff.
how about you?
