I have an attached -back sectional sofa with a chaise lounge. On the lounge, the upholstery on the attached pillow back has become unattached. I can see that it was originally stapled. Any tips on how to repair this myself, cheaply? If you write a hub, please leave a link here. Photos, tools needed, where to buy the tools, and instructions would be ever so helpful. HubPages is an ideal place to seek advice from everyday experts, after all!
