Dog collars - always worked flat?

[LeatherLegion]

     I think the padding is way to thick. With or without the top strap attached , a padding that thick will wrinkle regardless , when bent into a circle . If I am making a collar using two ply , I am always  gluing them together around a form. My padding is not nearly as thick of yours and I still get a bit of wrinkles . 

I am using different size PVC pipes as forms ... helps  me with collar sizing too .

The 6 mm padding is also according to JH Leather. For once I tried to folliw instructions... But I agree, I'll try 4 mm next.

@LeatherLegion Your collars are beautiful! The day I get edges like that I'll jump with joy!

The laws of physics say that if you fix two layers in the flat position and then bend them the inside layer will contract and the outside layer will expand. You have to glue/sew it in the curved position, either on a cylinder arm machine or if by hand on an appropriate shaped form. It will never lie flat after this. This should apply no matter what thickness the layers.

Exactly. Which is why I was surprised by the pro's work and asked the question in the first place.

But I suppose the explanation is that most dog collars are stored and sold flat. The wrinkles only form once on the dog and then they are invisibly on the inside... But martingale collars - the only type I am currently interested in - are always round anyway. At least until I find a way of adding a buckle without removin comfort or looks...

I always glue up in the round but then I use a cylinder bed machine barge cement when dry enough you can use a piece of parchment paper so as not to miss stick pulling it out as you go along just leave the liner long and wide cut it of after works good for me.

Are you talking about machine sewing? Not my problem I did glue my latest collar (not sewn yet) in the round, but I had marked the stitches flat beforehand. I think that should work. If I had the right thread...

       When you say padding , is that some kind of  foam inside your soft leather ? I am only  using  3-4 oz soft leather for my "padding" nothing stuffed inside  ...it is more for aesthetics  . If needed , the softer rolled edges are more than enough protection in my opinion

I sewed all of these collars flat. I used JH Leather video for directions. I used 1/8th inch closed cell foam inside the padding leather and hand sewed it. I haven't had a problem with not sewing with it curved.

Well, what does it look like on the inside when it is bent as around a dog's neck? While lying flat it looks good, see the laws of physics quoted above (isn't it rather geometry?)

Yes, I put foam inside the inner red leather as per instructions (and safety belt from a car wreck in the outer layer for solidity, my idea).

I have wondered about the necessity of padding, but for the moment I'm experimenting and learning, sometimes following instructions, sometimes not. Then I try the collars on my dog and we see what we like.

I think padding becomes most useful with rivets etc on the outer layer. Very soon I'll try a collar without any sort of padding, just to see what Rika thinks.

I really don't think the dog would feel the wrinkles in a collar, it's kind of like the princess and the pea.
