Remove the sash from the frame and pull it to the right until it's completely open. Cut the cord at the bottom of the sash and remove any nails sticking out from the end. Utilizing needle-nosed pliers remove the nail and place it into the side channel. The knot should be tucked into the cord into the hole and secure it using an nail set.

Re-install the sash and then install the beads for staff. Make sure you leave enough slack in the cords for optimal operation. Finally, reinstall the counterweights and balances. Decorators caulk is an excellent way to reduce the amount of draughts. Apply small amounts of caulk between the bead boxes for staff.
