Canva

Canva is a free, online design tool. It has its own tutorials on the Canva site - look for their "Design School". You will want this on both your computer and phone. It is pure genius in its ability to share content, but first you need to understand it as a design tool.

You will use it to create your own content and resources... and it can be used along with PowerPoint and/or Google Slides which pale in comparison, especially on the distribution side of things.

The banner of this site was constructed in PowerPoint... and the whole "feel" of this site is "So 90's". There is a reason for this: because it is. :-)

However, if you are new to this endeavor - you have the opportunity to learn new skills, and if you don't know either PowerPoint or Canva, learn Canva first.

Not much more needs to be said on this. Simply go there, take advantage of their training and start building your own "stuff" for posts, flyers, and graphic content that is congruent with the "brand" you will build.
