MOST I HAVE SEEN WOULD BE IN THE 5 TO 6 INCH LEGNTH. THE ONES WITH 2 TO 3 INCH ARE NOT LONG ENOUGH TO FLEX AND BEND AND DON'T LOOK GOOD AND SOME EXAMPLES HAVE FRAZZELED LOOKING TUFTS WHICH TAKE AWAY FROM THE NICE LOOKS OF THE SWORD.
I AM NOT SURE HOW THE HAIR IS PUT IN AS I HAVE NEVER GOT AROUND TO DOING IT. THE HAIR IS HELD IN BY A WOOD PEG BUT WEATHER THE TUFT IS INSERTED IN THE HOLE FIRST THEN THE PEG INSERTED OR THE HAIR ATTACHED TO THE PEG AND INSERTED TOGETHER
ANOTHER POSSIBILITY IS IF THE HAIR WAS LONG ENOUGH SAY 12 INCHES TO FIND THE MIDDLE AND STICK IN THE HOLE AND INSERT THE PEG RESULTING IN TWO 6 INCH TUFTS PER HOLE. WHEN THE JOB IS COMPLETE THE TUFTS ARE CUT TO BE EVEN IN LEGNTH. I HAVE PONDERED THIS IN THE PAST BUT NEVER GOT THE MATERIALS AND GAVE IT A TRY SO I LOOK FORWARD TO LEARNING HOW YOU GO ABOUT IT. GOOD LUCK
