you know you CAN slide the wires into the holes BELOW the screws if you really want to and it will work just fine. I have had to do this when I do multi twisted coils and the wire is too thick to get under the screws. That being said, if you're using just single wire then yes, wrap the wire around the screw head for a better connection. It's easy, and honestly if you CAN NOT build a kayfun...you might want to think about not building at all. Just sayin
