14. Tufting. Measure and mark with straight pins where you want each covered button placed. Then, following the package instructions, make eight covered buttons (using circles cut from leftover fabric scraps).
Thread a 10-inch upholstery needle with a 2-foot-long piece of waxed button thread and push it through the cushion from the top down. Then, unthread the needle at the bottom, loop a button onto the piece that is still sticking out the top, and thread the needle again at the top. Push the needle through about ¼ inch from your first entry point, so both ends of the thread emerge from the bottom of the cushion. After repeating this on all eight buttons, place the cushion face down on the floor. Stand on the cushion (which compresses it), straddling each pair of threads. Pull the threads tight, tie them in a knot, and trim the excess thread.
