Retro motorcycle seat

Spent a productive morning using Cheeta3d to model and render the seat for my v-twin bike. I find for the more organic shapes Cheeta3d is easy to use - example; after the basic shape is subdivided, the piping used polygon loop selection, extrude loop as one group, expand selection one step, then apply Catmull-Clarke subdivision! The stitching was done the same except for not preserving the group!
