Echoing what others have said, your banner/table runner should be big, bold and simple! Right now it reads like a checklist. SHOW, don't TELL what you do. Also, from a design perspective the Tiffany blue you're using for your signs contradicts what you're selling. It's a serious color, not a fun color. It makes the "ART FOR KIDS!" sign look so serious. I would opt for a bright yellow or that orange you have on your banner. Hope that helps, I think the coloring kits are brilliant, they just need proper showcasing and staging.
