Canva is a free site (although there are features that require payment to turn on, and for work purposes I've upgraded, most of what I've used in my day to day use of the site hasn't required shelling out cash). It's a drag and drop program that enables you to create graphics (signs, book covers, letterhead, business cards, social media posts, invitations...), and it's incredibly easy to use, very intuitive. There are templates (some free, some available for a small fee), shapes, fonts, grids, frames, illustrations, icons, charts, photos, etc., or you can easily upload your own elements and use those. Admittedly, it's more limited than something like Photoshop (I can't make my text glow or easily add a drop shadow without doing a workaround,but I also don't have to sell my house to afford the program or spend years learning all the ins and outs of how it works). Here are just a few of the things I've made with this handy tool:
A protest poster for a march I took part in
An idea for a cake design I took to the bakery
A book cover for a book I'm rereleasing shortly
Some Facebook posts
The outside and inside of an invitation
And those are just a few of the many uses I've found for Canva. It's one of my favorite places on the internet.
I hope you found this useful. Enjoy!
