how to move category description to bottom of catgory page

Hi

I’m using the Canvas theme.

The default in Canvas is to show the category description at the top of the category page, which looks ugly. I’d like to be able to have it at the bottom of the page.

Rather unfortunately I didn’t create a child theme before I started using this theme. I’m very new to this, its only the second blog I’ve built. There is a custom CSS folder which I thought would be sufficient, when I started, but I think I probably should have made a child theme. So frustrating.
