Step 1: Damage Removal
First, remove the cover from the cushions.
Next, using a seam ripper, remove the damaged portions of the cushions. Set the removed portions aside, you will use these as a pattern for the replacement fabric.
Step 2: The Cover Up
Using the removed, damaged fabric as a pattern, cut new pieces of fabric.
Turn the couch cushion inside-out. Pin the replacement fabric in place and sew around the edges.
Be sure that patterns face the same direction when fixing couches with multiple cushions.
