Place some felt on the floor. Put one chair leg on top of it. On the felt, trace the end of the chair leg with a pen. Cut out the quantity of felt pads you need for all of your chair legs.
Cut a 4-inch circle from a piece of non-felt fabric. Make the same amount of circles as you make felt pads.
Place one felt pad under each chair leg; then put a fabric circle under each felt pad. Pull the edges of each fabric circle up around the leg of the chair and wrap with a rubber band to secure it to the leg.
