Alright, I'm going to try to come off as unbiased as possible. However, I'd like to think that this free resource and I aren't on the same playing field. After deliberating over a few paragraphs, I've come to the fair conclusion that we are certainly not on the same playing field. I don't we are even playing the same sport.
Surprisingly, I'm going to start by telling you; you absolutely should use Canva or any other free resource you can get your hands on. If you're trying to do it all on your own, this is the way to go. It is very design-beginner friendly. I've honestly never used it, but I can tell from watching others that it has easy-to-use templates that guide you. It's cheap and just what you need to get started.
Unfortunately, everything I stated before is also where Canva doesn't compare to a designer. Like I said before, Canva is cheap. Therefore everyone has it, including all of its templates. These cookie-cutter templates start to look the same, leaving your brand without a chance to stand out. Designers are equipped with all the right tools to help you rise above the rest.
While studying graphic design in college, professors wouldn't even let us get on the computer until we had various design sketches for our projects. Behind one idea, there are trials and errors to get to the final product. Then, to put those pencil and paper sketches onto the screen, well, that's a whole other craft. Processes like these are what is lacking from platforms like Canva. A designer's methods will take your brand's core values and shape them until they are visuals your audience can feel. Most importantly, they are not limited to a template or a decision the computer makes for them.
Canva is good in a pinch or for just starting; anything beyond that, go ahead and give your local designer a call. They'll come up with a unique plan to meet your goals. After all, your audience comes to your business for its many exceptional qualities, don't confuse them with designs that look like everyone else!
