@mk22smith I'm actually not sure, but it should work for any six strand embroidery floss, not just dmc, if that's what you mean. It might work for thinner or thicker string too, but I have not tested it. It might work because when tying with thicker strings, you need more string per knot, but you also need to make less knots.
If it does not work, you can still try to figure out a formula based on this formula.
Does this formula assume/require that the string is normal 6 strand dcm to work? I'm working with a few different sizes nylon and paracord and having a nightmare of a time guessing lengths (I did well at first and got cocky, and now am either way over or way under). If it is not materials agnostic, I'll try to get an old friend who actually likes math to help me try myself!
@Jewelti thank you for you detailed feedback. I'm not sure I understand half of it (English is not my first language), but I appreciate it 😄
This method comes from experiments that I did. For me the variable 100 works perfectly. For someone else another number might work better, but I did not want to make the tutorial too complicated to understand. The formula isn't written mathematically correct, but that has the same reason.
I would recommend that you start out your experiments with the length you get from this formula. Measure what you have left over and then adjust the formula. That's what I did when developing the formula. I first made a bracelet, measured the string length, tried to develop a formula from it, applied that formula to another pattern, tied that pattern, measured the string length and adjusted the formula afterwards. I wish you lots of fun experimenting!
This is just one possible formula. Maybe you even come up with another one.
This is more of a scientific method approach than a theoretical one, which I think is probably the better one here. A theoretical approach might calculate the length to circle the width of a string and itself twice, and as string is squishy, the experimental results are more accurate, though also subject to knot tension. The only thing that threw my little nerd brain off was the first formula for knot percentage, because of the x100 in the denominator, because a) that's the variable x not the times x so I was trying to figure out what the variable in the denominator was and b) that being in the denominator means that your dividing into something tiny. As for the formula I might try the length thing with a few other bases and without the safety net FOR SCIENCE! later, so I'll get back to you if I do
@halokiwi ..Well, I tried to calculate the length of the strings in Pattern #131533... but I'm not sure if I calculated it correctly... so if you're free... Can I send you the lengths I calculated and have a look? Just so I know I'm calculating correctly °-°
I'm sorry, I'm so lost. For example, in the first string, it's +50% of what? I tried using my phone calculator to use 45 and ,50 and I couldn't get 95 with any type of calculation. I understand how to get the percentage, but not what to do with it??
