I'm making some journal cards for the upcoming November blog train. I used to make all my journal cards with rounded corners, Project Life style, but then I realized that having square corners makes them much more versatile - for example, even on various templates with 3x4 journal spots with rounded corners, not all have the same degree of rounding, so you can end up with a journal card that doesn't properly fit the space. But of course with square corner cards you risk cutting off important parts of the card if you end up clipping them to a rounded template.
It may be all-around more practical to make square-corner cards, but gosh, sometimes they just look nice with rounded corners. So I'd love for you guys to weigh in if you have an opinion or preference. If you have no idea what I'm talking about here are some examples of both kinds, and you can form an opinion on the spot if you like
