Hudson has a 1.5" minky fabric collar from Collar Mania. I really liked working with Lisa on this. It wasn't anything huge, or custom, or anything like that, but she was very quick to reply to my emails. So far the collar has held up great. Hudson doesn't wear collars a lot, mostly just to go outside to potty and then they come off, but he wore this one pretty much for 3 days straight as I tried to figure out if I like that width on him. No issues with it damaging his fur or leaving collar marks or anything like that.
But, yeah, if I do another fabric collar, I'll definitely look at what Collar Mania has because she was so easy to work with.
