One of the most head turning things you would see on the road would be a stretch limousine, all tinted dark on all windows, with matching police escorts, and perhaps a couple of small custom flags perched on both sides of the front part of the said vehicle. While the idea of a seemingly unusual sight of having that kind of vehicle driven around in public is certainly an eye catcher, anyone would definitely be curious as to what nationality is the VIP inside. This information directs the eyes of onlooker to the custom flags being flown.
Maximizing and giving your custom flags that edge over others would mean having them in key locations, and unobstructed to the direct line of sight. As for the case of the small flags on the vehicle, the idea of having flags on top of cars is rather unusual, therefore increasing the level of intrigue as to why use flags on cars. The attention one is going to get with that increased intrigue also increases, therefore achieving the amount of noticing from other people.
Having your placement of customs flags in more traditional places may also work, provided that the strategic locations of these flags are on the most unobstructed view, and highly visible where people expect to see them. For example, having your flags signifying Bible verses may be placed at the main entrance of the church. Since the churchgoers would be going there for a specific purpose – that is to attend service, having a specific passage delivered as they go inside would make an expected and direct impact.
Having them by the numbers may also work in your favor. Placing similar and custom flags in a straight formation would instill the same message over and over again on people’s minds.
