Common sense and "Be Careful!" will make it all very easy. I've been using the tube-dealies and the little tray-type deals for beaucoup years with no problem. The idea is to not be in a big roaring hurry. Take your time, be methodical.
Create a system and stick to it. Don't get distracted by TV or conversation--one thing at a time.
Any cliches I've forgotten?
"A cliche becomes a cliche because of the truth in it."
