My granddaughter told me about Canva.com. She is a teacher and she says it really helps her and it is easy to use. I will be working on a cover for a naughty book I wrote. LOL Yep I am a DOM… A Dirty Old Man!
I have used Canva before it is SUPER easy to use. It is free too. I like that you can save something and then go back and fix it later. I have never thought about using it for book covers. I have used it for the websites that I create. I think that it makes things seem neat and I can see where it would be a good idea for book covers.
