After a year of practicing tooling, I am ready to get down to business with my dog collars. I've made a lot of practice projects and "doodles." Now I want to try my hand at making customer-quality gear that I can be proud to put my name on. I'm designing the patterns for my example pieces and looking forward to making my debut. The problem: Right now, the only leather I have on hand is two sections of veg tan belly. I understand that's not ideal for collars which will see hard use, since belly tends to stretch. At a minimum, I need to use the belly to make example pieces for listing photos and prototypes to test with my own dogs -- that's unavoidable. Money is extremely tight. I'll be able to order a shoulder once the first order comes in, but I'm stuck with just belly until I get my first order. If possible, I would like to fix the stretching issue so that the example collars could be sold too without compromising on stability (rather than making them for example photos only and then being stuck with them forever as pretty paperweights). I've heard that using a lining would decrease a lot of the risk of stretch and minimize the impact of using belly. I haven't used a lining on any of my practice collars yet. I'm not finding much on Google -- lots of mentions of using lining, not much as far as specifics on how to do it. The questions: 1. How bad is the stretch when using belly? Are we talking "punch an extra hole" levels of stretch or more like "all of your tooling is ruined and you may as well dump it in the garbage right now" levels? How much force would it take to make a noticeable difference? 2. To what degree does adding a lining stabilize a potentially-stretchy piece of belly? 3. What type of lining would you recommend for the inside of a tooled leather dog collar made from belly? What weight of lining am I probably looking for? (I'm not sure of the weight of the belly I'm working with, but it was one of the thickest ones at the store if that makes a difference.) 4. Would doubling it over and lining the belly with another section of belly work at all? Can I take a "brute force" tack and just make it thick enough that stretching is unlikely without changing materials?
5. I've seen mention of using pigskin or cowhide as lining (although not in the context of collars). How would you finish that? Does it create a smooth seam if burnished to veg tan? Or do you just stitch it and rely on the adhesive to keep the edges tidy? If the latter, are there any special steps to take to ensure longevity? And would you attach the lining before or after burnishing the main veg tan piece?
6. Are there any good articles or videos on working with lining?
Phew, I think that's it for now. I appreciate you taking the time to read through this whole thing -- I know I'm full of newbie questions. It's awesome to have an experienced community like this to reach out to.
