it.
first you will want to rip down a couple of boards to 2"
take one of the boards and cut a 45 degree on the end perpendicular to the length of the board. now place the inside edge of the 45 to the outside of the leg and mark the other end of the trim piece at the out side of the other leg. you now need to cut another 45 on the end you just marked. repeat this process to get a piece for each side, you can test fit the pieces and if they dont fit quite right you can trim a hair off if they are to long.
