I hide the swivel inside the bait to give it a more compact and seamless look. Take the section you cut off the end of the bait and cut it to the size of the swivel, then using a hook and line thread it through the swivel and then the small section of plastic. Slide the section over the swivel while pulling the line tight then attach the blade. I went a step farther and melted the plastic back together with a lighter. I'm hoping to catch a few fish on these this weekend. At the very least I had fun in the garage playing with my toys.
