Snip any frayed edges away from the rip, using small, sharp scissors. This will make the area much smoother once you fix it.
Remove any stuffing poking through the torn area. Apply leather filler inside the area of the tear. This will help keep the stuffing in place.
Dry the leather filler with a hair dryer set on low.
Apply another layer of the filler and don't wait for it to dry. Leaving it sticky will help the patch stick.
Cut a patch slightly larger than the area of the rip, using scissors. Place leather glue around the site of the tear.
Place the patch over the rip, smoothing it with your fingers and lightly pressing it down. Leave it for an hour so that it dries.
Wipe leather protector over the patch with a cloth. Let it dry for an hour.
Apply a liquid leather color to the patch area, using a cloth. The color should cause the patch to blend in with the rest of the furniture.
