6-10-12" tiers stacked. All buttercream. Harley Davidson logos are image transfers glued to gumpaste plaques with piping gel then attached to cake. Bottom tier is wrapped with a ladies belt from Walmart. :) Hard to see, but the top tier has piping to look like the stitching on a motorcycle seat. This one was tons of fun to do! Thanks to Edna and Jeep_girl for help with the gumpaste questions!
