Duct tape! Lay it long ways along a stretch of damaged cord and carefully wrap the tape around the cord. If you desire extra reinforcement, cut some 4 inch pieces (tags) and lay them perpendicular with the ends of your taped section to prevent dust/dirt from getting in. Trim up your tape "tags" and you're done. BONUS! Use decorative duct tape designs like "hippy flowers" if you want to add a personal touch! EASY FIX!
