Always offer your best at the time.

I think one should always offer their best. That is the best job you can do on your present project within the restraints of time, materials on hand, and the amount of practice you have had on other pieces of a like nature. All of my work is OOAK--that is because the conditions under which I am creating are always changing. Each person will judge your piece differently. Soooo just do the best you can and you CAN BE proud of your work.
