Carousels may represent a different layouts. All you have to do is make all of your selections, (ie: your badges, ribbons, rank, etc) then you can switch back and forth to the different backgrounds and your signature will be generated depending on the layout of that carousel. For example if you choose a background from the "medium signature layout", that layout will be used. If you choose a background from a "large signature layout" then that layout will be used. The large layouts, usually the carousels near the bottom, will represent the ribbons in rows of 3.
