Writing an active-filled sci-fi, whimsical romantic novel, or reflective memoir is challenging and rewarding for many authors. What many enjoy a little less is worrying about the physical designs accompanying the book, especially if they're going the self-publishing route and need to create the cover themselves. If you're planning to write a book on Wattpad, you're going to want an eye-catching cover to grab readers' attention. Graphic design tools like Snappa make a book cover design super quick and easy.
