When you want that zigzagged sewn look, but don't want to fuss with pulling out the sewing machine or buying those sewn look rub-ons, then try this...
Take a piece of regular ribbon. At the cut end, grab a single thread and start pulling it loose. This will unravel the thread running sideways through the ribbon, and that has a zigzag look to it. You can then squeeze the top of your liquid glue bottle and let most of the glue go back down. There will be a tiny amount of glue left on top. It's just enough for you to gently stick parts of the unthreaded ribbon on top of, and then apply the zigzag straight to your page.
