A while back my Coonhound lost three sets of collars with tags in as many months and ended up wearing faded beat-up collars from the "old collar box". All of my dogs really needed an upgrade, instead of spending $40 for new collars I just ordered some nylon webbing and reused the old hardware, it upgraded all five collars plus bought enough hardware/webbing for 3 new ones for about $10 total.
It is a fun/quick project that gives your pack a spiffy new look for very little money. Plus if your dogs are not hard on their collars (mine are) t is easy to add a colorful ribbon to make a fashion statement. You can also make a "designer choke" out of webbing/ribbon and two D rings and leashes for walks/trips.
This site has what I think is the best pricing on webbing plus they sell every sort of buckle/adjuster/clip imaginable by the piece: https://www.strapworks.com The quality is good and their nylon webbing is UV resistant so it doesn't fade, that is important since I like my dogs to wear matching bright red/orange collars for safety (especially during hunting season), three have a reflective strip which glows brightly when hit with a flashlight or headlights "just in case".
One tip though, their "heavy" nylon webbing isn't really all that heavy and next time I will probably double it up for the larger dog collars. At .60 a yard the cost is just pennies. Also if you buy supplies at a fabric store stay away from fabric store d-rings, they are fine for tags but they will break open/fail at the worst possible time if you use them with a leash.
On the other end of the spectrum if you have a large or giant breed dog and want to spoil them with an elaborate high end leather collar for Christmas check out this site: https://www.fordogtrainers.com/dog-collars-c-66/ Their products are all custom made in Israel and the quality is phenomenal. My mastiff has the "Vintage War Dog Collar" and the "Royal Nappa Padded Braided Dog Collar for Fashion Walking" along with a couple of leashes.
They cater to the mastiff and working dog owners that like to "brag on their dog" plus they have a lot of high end gear for Schutzhund/Police dogs. Though some of their pricier padded collars are very thick/heavy and probably not suitable for dogs under 100 lbs.
