If you've been following along you'll remember that last time we put on the inside arms of our sofa. This time we are going to put on the inside back of the sofa (the part the cushions will be against).
Of course the first thing you'll do is measure the inside back of your sofa to know how big to cut your fabric. Remember to add two inches to each side. When you have your fabric cut lay it across the inside back of the sofa.
Here again you'll be making cuts to go around the sofa frame. Same as before you'll use the needle to get the angle of your cut. Cut one side at a time and staple (described below) then move to the other side and do the same.
When you have made your cuts to go around the top and the bottom frame, push the fabric through to the back so you can staple it to the frame.
Start in the middle of the side and staple out to the edges of the side. As always, staple a little out from the center and then move to the other side of the center. Staple one side completely and then move to the other side, make your cuts to go around the frame and repeat. For now don't staple the part of the fabric above where you made cut at the top. (We'll get that when we staple the top part of the inside back.) Next you'll move to stapling the top and the bottom. Same thing here, staple a little on the top, staple a little on the bottom, moving back and forth from side to side and top to bottom. The reason for all of this is moving back and forth is so that you can keep your fabric pulled tight and wrinkle free. The picture below shows the part of the frame where you will staple the top. Basically just pull it over the top and staple it to the piece of wood there. Staple it as close to the bottom of that part of the frame as you can. You'll need to staple cording here later and you don't want your staples to show.
The picture below shows where you will staple the bottom part to the frame. You don't have to worry so much about your stapling here, it will be hidden by the back of the sofa.
At the top where you made your cut you'll want to make a pretty fold and staple that down. The staples will hold the fold in place. In the picture below the fabric isn't stapled down yet so forgive the pucker, it is more to show the fold. Also: you might need to cut out a little of the extra fabric when you are making the fold. Just be sure and not cut too much out.
When you have your fabric stapled on all sides you'll want to cut off your excess.
And there you have the inside back of your sofa! (my apologies readers, I neglected to take a picture.)
