After purchasing my first mig welder ( Lincoln 140) I discovered that I needed a weld shield. I checked online and the ones worth buying don't come cheap. So I took a design I saw in Google images and made one that anyone can for much less using strong thread or fishing line, grommets, a sheet of thick plastic sheet, two short metal rods, two small hinges, two small 'L' brackets and an old aluminum clothes line. It works great and is easily erected on or removed from a bench top. Sorry the photos aren't better but you get the idea. If anyone needs better photos, let me know.
