Knife shoulder holsters?

[KristineS]

I got a request for a double knife shoulder holster, similar to this. 

Can anyone tell me what is the best leather, i understand i cant use chrome tan for the sheaths, but would it look ok if i combine veg for the sheaths and chrome for the straps? 

And does anyone have a pattern? I havent had time to even consider learning inkscape, and i would be willing to pay for a pattern. Or if someone can provide guidance, I totally appreciate any help. 

Thank you!

Andrew custom leather uses garment leather for his shoulder harnesses and veg for the holsters.  His shoulder harness is suppose to be a good one.  His design doesn't require belt loops either.  You can look it up on hank strange videos.  He has a how its made video of the monarch shoulder holster.

The retainer tab should face backwards, not forwards, where it'll constantly catch. I'd like a neodymium magnet near the tip to support it, without delaying the draw.
