A few years ago Ed Scott taught me this quick way of making a string out of b-50. He called it the "Scott Twist"  Takes less than five minutes.
 Start with 3 bundles of 5.                            Twist each bundle away from you. Then 1 bundle over the otner 2bundles(1 over 2and3,  2 over 3 and 1 ...) 20 or so times and keep twisting each bundle  as you lay them over the other 2.

                                                              form a loop and pair the bundles by twisting them together

Then make a simple braid until your past your tag ends.  Tie a bowyers knot for the other side.  Simple
