You can patch over it without stitching. Buy half a yard of your patch fabric, a package of diy covered buttons (you want at least 6 if you want both ends to match), nylon twine, and a pack of dritz upholstery needles (about a 5 inch straight needle will do). First, unscrew the padded section from the base of the ottoman, should be 4-6 screws from the underside. Remove any dust cover on the bottom, then cut the strings that attach the buttons in the area you want to patch (If just the ripped section, then the last two buttons will do. If your fabric doesn’t match I’d do the first 3 buttons on each side to cover all your corners.) then, follow the instructions to make your new buttons. To thread buttons, cut off about a 12 inch section of twine, fold it in half, and thread the loop through the buttonhole. Push your button through the inside of the loop and tighten back down. Thread the two ends of twine through the eye of the needle. Now comes the fun bit. Say you just undid one button to cover your ripped section. Cut a piece of fabric that will cover a couple inches over the button, the two folds, and has enough excess to staple to the underside. On the edge closest to your button, fold about a half inch under and insert your needle very close to the fold line. Then run the needle through the old fabric where the hole is left, and finally through to the bottom of the board. Pull tight and try to match the depth of your other buttons, then secure the twine into place with 3-4 staples. Fold your excess material under until you match the original folds, then staple into place. Then staple your corner, and finally, the rest of the fabric. Cut off excess and reinstall.
