Do you live close to me???? I NEED a carriage upholsterer!
That sounds like what I paid for mine. My hands don't work very well, so I have a hard time using synthetic lines. My favorites are made in Ohio by a really nice Amish man, and they are garment leather wrapped around regular leather. THE best!
I have old Zilco harnesses in my barn that look like crud after only a couple of years, and cost over $1000.00, and my Amish harness still looks good after 5 years. The Zilco traces stay a little more flexible in the cold, but that's about it for advantages to me.
Are the traces continuous with the breast collar, or do they buckle in?
So glad it is all going to come together for you!
