I found this video to be quite informative for refinishing the back of the sofa without having any staples show. I liked that the video for finishing the back of the sofa because it was brief but packed full of good information so I am providing a link to her Youtube channel where you will find her other videos. Be sure to check out her video for finishing the arms of the sofa too.
Okay, before you begin you may want to know a bit about the fabric choices out there. Make sure you pick a heavy duty durable fabric for your upholstery project. Before you run off to SAS to get your fabric check out this yardage chart. Make sure you buy enough fabric to finish your project because you may not be able to find the exact same fabric at a later date. It is better to have too much than not enough.
If you get started and then realize you bit off more than you can chew check out the bulletin board and customer window at the store to see if you can find a professional to give you a hand.
Once you are done with your project, please post before and after photos on our Facebook page to show off all your hard work.
Best of luck to you. Happy reupholstering.
Take care! : )
