My lower back says it is time to take a break from leaning over the table folding hems. Rather than lose the time, it was a good alternative to start making the stack lines.
The Board gets wrapped with string (150 pound strength Blue Line Spectra) 60 times. That is enough for 20 kites. It is always good to have spares.
Then the string gets marked 5" away from where it will be cut.
Then it gets marked 5" the other way.
After it has been marked 5" to either side of where it will be cut, it is cut along the line in between.
The result is 60 strings, all cut the same length, all with 2 marks exactly the same distance apart. Now it is just fold on the marks, tie overhand loops in the ends, and they are ready to be stretched, matched in sets, and installed.
