I really don't want to overcrowd the banner, especially if there is a lot of detail for the background, like my banner that Wonder made for me. I would say two is comfortable, three is pushing it, four is stretching it, five and over is too much. Especially at the size you want it at. I would suggest that you give me like five or six and your preferred and see how many I fit while still making it look nice. Does that help?
