I am .. um.. not used to working with chain. I don't quite know how to get the chain attached to the d-rings. :( I thought I would just twist the open ends apart, but I have only one pair of pliers (what? I could have sworn I had two.) and the chain appears...erm... stronger then me. I DO have bolt cutters. Worst comes to worst, I will just snip off a little bit of one end (at the join of a link) so I can just force the d-ring through the gap.
