Things You'll Need
Instructions
Hang the bridle from a peg or nail so that it hangs flat. Position the bit so that the curve of the bit faces out or up, not in.
Working on one side at a time, tie a "snaffle bit" -- a bit with one ring on each end -- to the bottom bands in the leather bridle by pushing a leather or nylon string through both the ring on the end of a snaffle bit and the leather loop on the bottom of the bridle. Tie the bridle to the upper two rings of a curb bit.
Tie the reins to a snaffle bit after attaching the bridle. Attach reins to the lower two rings of curb bits.
