So when I am writing I have two- three scenes happening at once...should I put a border in the middle between these scenes? or should I leave a blank space between scenes? Opinions and advice much appreciated. Im trying to decide

I think it would depend on the border. You wouldn't want the indicators to be distracting, but they can help the reader notice the switch in plot more readily. I just leave a blank space, but that's just cause I don't know if I'll add a border later on. It's completely up to you though hope this helps

Thanks

You can just put a few spaces in between, but some times those can get lost or you can forget there was supposed to be a scene change there. Standard scene breaks include a row of astricks: *** or, in the publishing industry, a pound sign: #

I generally just do a double-paragraph break, and am used to seeing that in books. Borders are also common and can be done, but, at least in my opinion, double paragraph breaks work as well.

In books---the final printing that readers will buy and hold in their hands---a blank line between paragraphs, which I learned to call a "typographical break," is traditional, though some books use a symbol of some kind instead. In a manuscript, this should be indicated more explicitly, by a row of three asterisks or a pound sign. (In the old days when a manuscript would go to "the printers" to be typeset, a row of three asterisks or a pound sign would signal them to insert a typographical break.)

Hey thanks for the tip! I will keep that in mind when it goes to publish
