My fav is a mechanics part tray. Picked it up at a parts store for 3 bucks. Its round,about 6inches in diameter and the entire bottom is a HUGE magnet. I can put my heavy Ginghers in the tray turn it upside down and the scissors wont fall out the magnet is so strong. Have it on the end of my ironing board and drop my pins as I press. Have to keep it far far away from my machine! Love paper clips too, have them taped all over my machine so I can thread specialty threads in different directions for the best results.
