Creating Social Media Graphics
Learn how to use PicMonkey and Canva to create your social media graphics. As of September of 2017 PicMonkey no longer has a free version. However, they do have a free trial and their monthly membership rates are very reasonable. Even if you joined for only a month to create all of the graphics you need, you are still getting an excellent deal!
