Sometimes, a story is best illustrated with words instead of pictures. When that happens, typographic book covers are a great option. Go the text route with Canva for your Wattpad series for the maximum feels and even more likes.
This text-driven cover is a great place to start for teen fiction. Just plug your title in and you're good to go. Or you can customize by editing the font style and colors. Canva has over a hundred fonts to choose from, as well as a large selection of ready-to-use typographic designs ready to be dragged and dropped into your layout.
