I don't really care for the plastic chains and metal ones are too heavy and also expensive. So i tried an experiment last night and cut 3 links out of plywood. After rounding the edges, I split one link and inserted the other two then glued it back together. The result came out fairly good and once painted should look really nice. Now I have to see about building a couple jigs to help mass produce the links quickly vs. having to cut each one out by hand. These were made from 3/4" plywood. The links are 2 3/8" by 3 1/2" each. Will also have to try making links from 1/2" and even 1/4" plywood to see if I can make smaller linked chains.
