You may also wish to insulate your rafters, and this is an excellent opportunity while you are dressed in safety gear and the attic is clear. Unroll your insulation as before and stuff it in between the rafters, just like you did on the attic floor. Hammer several nails into the side of each rafter, tight up against each roll of insulation to prevent it from falling down.
Congratulations, you have now fully insulated your attic. Prepare yourself for a warmer home and reduced energy costs!
