I really love this resource, and I'm not just saying it for the sake of saying it. If you like sites like Undraw, this is for you. Here's a few reasons why:
1. FREE. Seriously. This stuff looks good, and it's free. What's more to say?
2. You can change the colors for different elements of the graphic. You can change the color of an entire batch of graphics, or individually.
3. Download in both. Svg and. Png formats
4. Free for both personal and commercial use, attribution not legally required. Use it for your flyer, your brochure, anything! It's all for you.
If this doesn't convince you to use this resource, I don't know what will. I've used this to create social media graphics, and you can too!
