You can stopping chasing small parts all over your shop while working at the bench, and while seated. An old watch makers trick is to attach the bottom of your apron to the bottom of the bench so the parts drop into your lap and not onto the floor. I used the loop part of Velcro attachments sewn to each corner of my shop apron and glued the hook parts, spaced accordingly, under the front of my bench. Sure saves a lot of time crawling around on the floor. Not to mention trying to find the part that gets legs and runs to a secret location somewhere in the shop, never to be seen again.
