WAXING LINEN THREAD
Like all thread, linen thread has a tendency to tangle. Waxing sewing thread with beeswax keeps the thread from tangling and helps the thread “grip” the paper. Run the thread through a cake of beeswax two or three times to coat it with wax, then run the thread through your fingers. The heat generated from the friction will melt the wax into the thread.
MEASURING THREAD LENGTH
The length of thread needed depends on the height of the book and how many signatures need to be resewn. Save time by measuring the thread directly on the book. For instance, a book with one unattached signature will need a piece of thread that is at least three text block heights long plus one text block height for tying knots.
ADDING ADDITIONAL LENGTHS OF THREAD
It’s not a good idea to try to work with more than 4 – 5 book heights of thread at one time. There are two ways to add additional lengths of thread discussed in the post about knots.
LOCKING THE THREAD ONTO THE NEEDLE
It can be very frustrating to have a needle fall off the sewing thread in the middle of a repair. Here is a method to lock the needle onto the thread before beginning a repair to assure the needle will not fall off during the repair.

  • Thread the needle as usual.
  • Grasp the leading end of thread (the end that was threaded through the eye of the needle) and wrap it around your thumb.
  • Carefully pierce the thread with the needle against your thumbnail.
  • Pull the needle through the pierced thread.
  • Hold onto the sewing thread and pull until the pierced end is tight against the sewing needle.
