These are called "ribbon rules" and they are very handy indeed for using in digi scrapbooking, for digital art, and for dividing sections of webpages or blogs.
These are "Halloween" and autumn color combinations. Each rule is 776 x 8 pixels or so (although the "properties" tab when it's clicked in the blog is indicating differently -- it's wrong), and what is shown below is not as long as they are in reality, but you can get the feel of the ribbon by the section shown.
