this instructable demonstrates how to hide a wire inside a wall with carpeting. it does not involve any carpentry, plumbing, or dog breeding at all. it is especially useful for making rooms look nice, making sure cleaning ladies/ moms/ girlfriends/ wives/ insane llamas don't rip up wires in an attempt to "clean up".
Step 1: placing the wire
first, you will need to find where your wire will go. try to find a place where there are not many turns, because that will make it harder. if it is going to go all around a room, you will need quite a long wire, so prepare for that.
