Canva is the most extraordinary design tool. I've built everything in Canva from flyers and logos to children's workbook sheets and presentations. There is literally nothing you cannot create in here and the feature set for the price is unbelievable. They also have a mobile app you can download to do designs on your phone, as well as presentation format and publishing graphics directly to social media. There is nothing like it online right now and it's oh so powerful. Canva turns non-designers into designers, and with the thousands of templates they offer, everything you make should look pretty good.
