B-fishy, first of all welcome to Crappie Dot Com from South Louisiana. Where are you from. There are many here that us multiple jigs on lines, as high a 4 jigs. You can use some form of loop knot for the top jigs and you favorite knot on the bottom one. Some also use the palomar knot for the top jigs. There are many here that can guide you better than I. Also you will learn more than knots here. Good luck in your fishing and we will be looking for reports.
