And you want something custom that is what we do here at Tool Awl leather 
above are different colors I can make this design in. that are washed look  even black
also if you want a wider strap let me know I can do that as well

When you bought or built your guitar did you cut corners and get the cheapest equipment for your guitar or bass? so why not get the best strap or pick guard that you can get 
These guitar straps and pick guards I make are from 100% veg tanned leather Hermann Oak leather. These are all hand tooled, designed and dyed. (Not some rolled design on a piece of upholstery leather with felt sewn between the 2 pieces of cheap leather. All leather used by Tool Awl leather is real cow hide tanned the right way. These are meant to last for years to come. So when picking a guitar strap do you really want some cheaply made lets make 300 a day, or one that takes days just to tool and made to last. Each and every one is different
