I am wanting to cover my couch. The problem is it is an old couch with very little padding. All of the slip covers now days are for very padded furnature. I can buy a slip cover, but it won’t fit my couch. Can any one tell me how to put extra padding on the furnature? I don’t know what the padding would actually be called either so that I can go buy it and how much would I need for the arms and the back. I would also like to have more of a cushion to sit on. Do you have ideas on how to accomplish this also. In total, I have a couch, love seat, and recliner that I would like to recover and have extra padding added to them. Thank you for any advice you may have.
