Just want to mention something in addition to the video … where I tell you to download the PNG … I didn’t realize that when I download PNG’s from canva I have the option to download them at full resolution (you can slide the resolution slider all the way to the right) … since I have the pro version.
You will be OK still using the free version but if you really want to have the clearest quality, get the pro version ($12/mo) so you can slide your PNG’s to max resolution. (or alternatively downloading as PDF and then converting to a high res JPG).
