With a long bight in the rope use two double loops to tie a Figure 8 knot. Then pass the end of the original bight under, up, and over the whole knot. Pull it tight to lock the two loops.

Structure: The Double Figure 8 Loop (ABOK # 1085, p 197.) is based on the simple Figure 8 knot.
LoopSize: In the animation the two loops have been made small. In practice they are usually much larger.
Other Names: The Double Figure 8 Loop is also known as Bunny Ears or Dog-eared loop.
Uses: The two loops can be used as an improvised seat. The Double Figure 8 Loop has also been used to equalize the load in a top-roping technique using two anchors: with loops that are made very unequal, the much larger one is passed around both anchor points. The center of this loop is then secured with a carabiner to the small loop. During rappelling, this spreads the load between the two anchor points. Recently, however, this use of The Double Figure 8 Loop has been discouraged because if one anchor point fails, there is enough slack to create a large shock load on the remaining anchor point, possibly causing it to fail as well.
Stability: Compared to some of the other double loop knots, e.g., the French Bowline, the Double Loop Figure 8 is stable. It is unlikely to slip so that one loop gets larger at the expense of the other loop.
