Good idea! I tape some paper/tape with my painter's masker tool to the wall just below the hole with the corners pinched and taped up to catch it. Throw away is quick and easy. The H.F. multi-tool (electric) is quick and easy, also for cutting/patching base and casing while in place.
Be safe, Gary

They leave a residue that impedes air-flow, costing you money.
Clean the ducting in the last six months? 17,000 dryer fires annually!
