discs, from right to left.

through about 3 or 4 inches.
Hold the end of the upper
thread loosely and turn the hand

two spools of thread, matching or
contrasting in color, one on each
spool
pin, lead both threads
through top thread guides, bring
threads down and pass one thread
between the back discs and the
other between the front discs, then
treat both thread as one until

needle eye of twin needle.
