That looks great. I think it'd be neat to take another image--like a landscape or something--and use the stencils to create a decal for that space. Did you essentially create stencils based on the bumper, then use them to cut out a flag decal for the spaces?
Job Well Done! Some projects are well worth the time and effort! I generally don't like putting decals and stickers on my vehicles, but I would make an exception in this case. Has anyone seen any of these for sale?
