Upon playing around with Style Editor in Squarespace (Design - Style Editor), while you are on your project page, if you scroll down to "Page" you can tell it to "Show Project Description" and this will allow you to insert copy at the top of your project page. To input this copy, go back to "Pages" and hover over the page in the navigation menu/page list on the left hand side, and click on the settings icon. In the Project pop out box, just add your copy to "Description" and tada!! I hope this helps!!
