I keep a lint roller with my sewing supplies and roll it over everything in sight, when I am through sewing for the day. I even roll it over the carpet in the sewing machine area to pick up the threads from the carpet so they don't wind up in the vacuum cleaner brushes. I keep a separate lint roller to clean up any loose threads from a completed quilt top. My sewing machine is not computerized, so I can keep a magnetic wand nearby to pick up any loose pins, including any that fall on the floor.
