Now and again you may need to secure a secondary line to a primary that’s under load (without slippage), so that tension is relieved. Usually the secondary is smaller as shown here. Start by taking a turn around the primary with the secondary (1) and then—the critical step—go around again in such a way as to wind up with two turns (2) around the primary lying next to each other. Finish off by continuing on with the bitter end of the secondary and making a half hitch (3) on the primary as shown. Strain is taken in the direction that’s away from the half hitch you just added.
