Fortunately, I have a friend with a sewing machine who is very talented who helped me sew together the pieces of fabric I had cut. I used the old seat cushion fabric as a template for cutting my new fabric, taking care to position the fabric to emphasize the floral pattern and so that it would be centered on the seat. When I cut the fabric that would run around the side of the cushion, I tried to match it up to the top piece. I bought a flexible welting cord that my friend expertly sewed into the bottom strip of fabric and then attached that to the top piece. Typically, the welting is sewn inside its own separate thin strip of fabric and then "joined" to the top and side pieces of fabric. Instead, I sewed the welting cord into the side pice of fabric and attached that to the top piece. In the end, it worked out perfectly, especially since I made sure that when I originally cut the pieces of fabric I allowed extra leeway for the inside seams. Then, it was time to stretch the newly sewn seat cover over the seat cushion. The best way to do this is to hold it taut, but not too tight, and prepare to use a high-powered staple gun to insert a tack at the front of the cover and when it's being held as taut as possible. The only way to do this is just to get in and get to it! Next up: inserting tacks around the base of the new fabric cover, trimming and using hot glue to apply a new braid trim.
