Do: Line images up. I’ll never forget my layout teacher grabbing a ruler and making sure that everything on my page lined up some how. When you see bad design, Most people won’t know why they don’t want to look at it, but subconsciously what’s happening is that their eyes (and brain) are working extra hard to make sense of things that are almost aligned, too close, or nonsensical. A lot of it has to do with gestalt principles, but just take my word for it: if you’re going for order, commit to it and line your stuff up.
