No matter if its wood, carpet, concrent or woven mat my tip would be if a part hits the floor, dont stand up or roll your chair till you know you are not gonna step on/roll over the part.

I have also made the switch from paper towels (or whatever you call them where you are) to cheap tissues.

Way more convenient to have a small box on hand, especially when brush/airbrush painting.

I still have paper towels but use them if im workin with decals/flocking/pigments where i have time to setup a "drop sheet"
