connecting wires?

I use in-line wire strippers that I purchased from Radio Shack a while ago

I use utility knife to create a fish eye in the middle of the strands of exposed copper wire -- creating two identically sized bundles of copper wire. I then feed my stripped end of the wire to be tied into that factory into the fish eye, SPLIT THAT wire that I just fed in there into TWO equal bundles and bring each bundle around the sides and twist tie them on top, solder, and snip excess and then tape or heat shrink.  About as solid a connection as you can get -- once you get the hang of it, it doesn't take that much time.  This method becomes challenging when you're working with smaller gauge wires or when your wire looms are in weird, tight places.
