Miriam, TSC has the magnetic dishes in 2 sizes that I use for my sewing stuff. you put a screw in the dish it won't go anywhere. Harbor Freight might have them too. I bought 2 or 3 sets because they were on clearance for $5 each set. I was nice and gave DH a set for his shop. I also got a couple of magnetic sticks ( they pull out and you can pick stuff up off floor or from behind an immovable object if necessary. Sure saves on my back.
