|I tell all of my students and friends who sew this important thing. When you are tired your judgement is not good, your patience is short and your project will more then likely end up in the circular file or the "hell freezes over" pile. We are all junkies, so here is what you do: Get a good stopping point (take 3 to 5 minutes), don't clean up, put the project down and get some rest. Your project will be there when you return to it. For those of us who work in thie field and can't stop - you can step away from the project. 30 to 45 min. is a good amount of refresh time. Eat some food and get the blood sugars up, (especially if you have been up all night ;-), read a magazine or the paper. After that you will be refreshed and ready to attack the finish line. The better you feel the better your project will be.
