Leather is a popular material used for furniture since it is sleek looking, cleans easily and normally does not tear. Since your leather sofa is probably exposed to so much use, minor tears may happen over time. If a rip or fine crack in the leather should occur, you can repair it yourself without having to send the sofa away for outside repair.
Remove the loose fringes of leather and fabric located around the torn area to clean it up before making the repair.
Apply a thin layer of leather filler inside of the hole, and then use the hair dryer on its lowest setting to help it dry quickly.
Apply another layer of filler and let that dry.
Place a small amount of glue on the leather fabric surrounding the hole.
Firmly place the sub-patch over the hole. Only press on the edges of the patch and not on the centre, since it will sink into the hole.
Dab the corner of a soft cloth into the leather protector, and gently swipe it over the patch. Allow it to dry.
