premise: How can I keep paint off my carpet when painting my baseboards?
hypothesis: Roll out 2-in. wide packing tape so its upper edge rests about 20 in. above the carpeting on the baseboard. The tape should rest lightly on the baseboard so it doesn’t adhere. Then tuck this edge down behind the carpet edge, first with your fingers, then with a wide putty knife. Remove the tape carefully after the paint dries.
