 doughnut charge. Cut one 18 inch piece of 50 grain per foot debt cord. Cut one 24 inch piece of 50 grain per foot debt cord. Use a 24 inch piece of debt cord to tie a five wrap yule knot onto the 18 inch piece of debt cord. Fold the 18 inch piece of debt cord to form a loop. Use electrical tape to tape the ends of the debt cord together. Use a piece of tape and make a sliding tape knot on the debt cord loop. Take a six inch strip of tape. Fold a two inch section over upon itself to create a nonstick surface and wrap the tape around the debt cord. Continue wrapping until the tape is finished. Ensure that the tape knot slides easily on the debt cord loop. Slide the tape toward the end of the loop to provide enough room to slide the loop over a door knob. Ensure the yule knot and tape slide freely. Direct prime a single cap to the running end of the loop.
