I bought a large kitchen tray, like you would keep your silverware or cutlery in. I keep it right beside my sewing machine and cutting board. When I use something, I have learned to put it back in the tray. It helps so much, but requires self-discipline to avoid the searching frustration.
As far as multiples, I keep a duplicate set of all the basics I use constantly in a travel kit to take to workshops and retreats. It was so frustrating to get there and realize I'd left something important at home.
