Here is what happens to me more than not... I really enjoy "creating something out of used" so I get an idea in my head and run with it. Sometimes it does not work out as I planned in my head, but looks beautiful anyway. It probably will not get finished, but I will keep it and refer back to it as my learning piece. I think we are toughest on our selves... I am my worst critic.. and desire praise... hehehee... so let it roll off your back.. which is hard.. but none the less have to do it.
