Simple Project
I started with almost 4' of threads to make a 1 foot usable length of cordage.  In the middle of the 4' of the yarns I braided for about 2".


I folded the braid in half to form the loop and re-strung the braiding disk with doubled threads.


I braided until the ends got too short and ended up with a 1' long section of braid from end of loop to end of braid.


If the doubled cord is too thick you can thin it out.  After the first few rounds you can start cutting one of the strands in each slot.  Do this gradually maybe one cut every other round and the braid will thin out.  The ends will be hidden in the braid. 


You can make a very useful soft shackle with this  braid.  Tie a knot in the end and put the knot through the loop end.  A very handy way to hang items from a belt or anywhere else.
