The Magic Thread Trick
      This is very simple but it does require forethought to use effectively. You need about 18 inches of thread that is approximately half the thickness of your working thread. Working with a contrasting colour can be helpful. Double the thread to form a loop. Think about where the loop has to be in order to pull in your ends because if you put it in backwards it won't work.

      Lay this magic thread alongside your centre or "core" thread, tatting over top of both this thread and the shuttle thread. Finish up to the first half of the last double stitch. Finish the last half of the stitch tatting over the core thread only.

      Cut the ends leaving a short length to pull in. Pull the tail of your Magic Thread until there is about a one inch loop sticking out. Thread the ends halfway through the loop. Pull the tail of the Magic Thread until the loop pulls your finishing ends in to the centre of your ring or chain and comes out. Make sure the finishing ends are pulled tight and cut close staggering them if they are too bulky.

      I prefer to pull ends in at different places to reduce bulk. For example, if my last round finishes with a chain joined to a starting ring, I use 2 Magic threads; one in the starting ring and one in the finishing chain. This means that I have to place one of my magic threads at the very beginning of the round, but it does result in a finish that isn't thick or lumpy.

      Your finished ends will replace your magic thread so if the doubled thread isn't quite thick enough, you may want to add an extra bit of thread as a spacer that can be removed before you pull your finishing ends in. Thread that binds or breaks is useless, so you want to make sure that the thread you use is both strong and slippery. Polyester thread and dental floss both work well.
