For certain types of rooms and some aesthetic tastes, exposed concrete flooring is a nice option. You can get concrete with a pigment color integrated into the material, you can paint the concrete, or you can simply use a clear (non-toxic) sealer for a more modern or industrial look
Professional woodworkers often don’t use pads on their clamps because they know how to set them up without marring the wood. But if you prefer to use them for pipe or bar clamps, you can buy some or make up your own. Scrap rubber, shoe soles, even old mud flaps, can do the trick. For pipe clamps, cut out a slightly undersize circle to fit over the pipe using a sabersaw. Next, cut out the perimeter about 1/8 in. oversize. Then make a slit in the pad bottom so it can stretch over the pipe without taking off the jaw end.
