The furled leaders I make for my use are 7', but, if I were making a 6' furled leader, the distances between my pegs would be:
25" between Peg #1 and Peg #2
30" between Peg #2 and Peg #4
30" between Peg #4 and Peg #3 (#3 peg is the tippet end Peg)
This gives you a length of 85"
Minus 10% after twisting gives you a length of 76.5" which divided by 12" gives you a furled leader length of 6.375 feet. After you make a shorb loop in both ends you should have a 6' furled leader or very close to it. All material will be different, but, you should be pretty close to 6'.
Hope this helps....

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
