Starting My Leather Journey

[Reccymech]

Currently my 'cottage industry' is sewing webbing, comprising tool rolls, bags, dog collars & leashes etc. I now want to expand into leather dog collars.

See attached rather poor photo of the 'Concept of Ops'. Now, I have a commercial sewing machine (Zoje...Juki knock-off), but I want to probably hand sew the dog collars. So, my question is what array of tooling I would need to accomplish the leather collar, as shown. Also, if I was to attempt it on my sewing machine what needle size and thread size would I need.

Ok I will give a shot at this. 

Tools I would want.

Leather edger.

Skiving knife.

Stitching groover.

Burnishing tool for burnished edges.

Stitching awl or Stitching chisels. 

Leather knife or razor knife.

Rotating hole punch.

Lmao I'm sure I'm forgetting a bunch of stuff.

What Juki clone do you got? 

Thanks.
