"I'm making a Google Doc for a newsletter, but how do I create 2 columns on one page?"
That is a great question, and I've actually been asked twice this week for the answer! You'd think that Google would have added that to their toolbar by now, wouldn't you?! When they ask me for my opinion on the matter, I'll be sure to tell them for you (*insert eye roll*).
The first step in this process is to sit on your free hand, because once I tell you how to do this, you're going to want to slap your forehead and mutter, "Duh." Once that task is accomplished, all you have to do is insert a table. Click on the Table menu, then "Insert table." Drag the mouse to the array size you want, most likely in this case 2x1. Right-click (or ctrl+click) on the table itself, choose "Table Properties" from the menu, and then change the border color to white. Here's an example of what it looks like:
You can add as many columns (or rows, if you'd like bigger space between them) as you wish, an no one will be the wiser!
