Good morning, afternoon or evening!
So I was trying to find some information needed for my project and I am absolutely sure that somebody must have taken needed measurements at some point, but I just can't find them. I would be very grateful if somebody could kindly share with me the following information:
? how much thread is used for fb and bf knots?
? how much thread is used in other knots?
? how much thread is used when a knot is tied ON it?
? how much each knot/row adds to the bracelet?
I would be very grateful to the person that provides me with this information!

You'll have to find that out yourself since it depends on how tight you knot, and on what kind of string you use. It even depends on the knots used for the pattern sometimes. Some patterns can be knotted tight, some less tight. That's usually because of the amount of bf- and/or fb-knots in that pattern.

Someone once posted a formula though, have a look here
