By using the same suppliers and the same manufacturers Jade Rope elimnates the chance that a difference in manufacturing approach or process will result in a different type of rope. However, because natural fibre ropes rely on raw materials the 'key input' (natural fibres) do vary from season to season, and thus each new batch of rope always has slightly different characteristics.

There are two main ways natural fibre ropes will vary:

1. The thickness of individual fibres (impacting the overall rope diameter)
Individual fibres typically vary from 0.015 to 0.020mm, when woven into single ply yarn this diffence in thickness is multiplied by each fibre used. A single ply that consists of 30 fibres can therefor have an overall diametre between 0.45 and 0.6mm providing an overal potential varience of 0.15mm. This is compounded when three reels of three ply yarn is used to create a rope. Even if the varience is only 0.05mm in a single ply, when three single ply sections are combined to create the traditional three plat twisted rope, the total variation will be a minimum of 0.45mm and can be as much as 1.35mm (quality control typically avoids the later larger fluctuation, but all of our suppliers stipulate a 0.5mm variation as standard).

2. The colour of individual fibres
Colour is  most affected by the available nutrients in the soil that the plant is feeding off. It is worth noting that even if the plant is growin in the same exact place, there will be variations in the concentrations of the nutrients available and potentially even a difference in the type of nutrients depending on what kind of soil management practices - if any - have been employed since the previous crop depletted the nutrients.

There are also other smaller considerations to be mindful of, for example the following chacteristics will also always differ slightly from crop to crop: Average length of fibres (effecting strength and durability), rigidity, and texture.

Why Do These Differnces Occur  

There are many reasons why hemp and jute plants themselves are never identical, we've outlined the main contributing factors here: 

Available Nutrients 
Our hemp is source from developed 1st world countires and thus has a more 'stable' growing environment, but both our jute and linen raw fibres are sourced from India before being manufactured in Italy. These later two crops show regular fluctuations in colour due to the 'looser' farming habits in the sub continent.

Rainfall
The impact higher or lower than ideal rain fall is also a signifcant factor that effects the plants rate of growth and it's fibres overall integrity. Flood or extended periods of drought can cause havoc on an entire harvest causing perhaps the largest changes.

Seasonal Factors
Even shifts in average or normal tempratures can either slow or excelerate plant growth, and both slower and faster growing plants tend to result in fibres that are not the 'norm'.

Harvest Times
There are two different planting times, late March & early June, although planting can occure throughout April and May. Because the growing cycle is an average of 120 days the differences in climate plants are exposed to when crops are planted 2 months appart does also impact on the quality of fibres.

These are just the four key impacting factors, so you can see how easy it is to have small variations from harvest to harvest, and thus understand why all batchs of natural fibre ropes will fluctuate in diametre, colour, and even look and feel.

All we can do is advise you to purchase your 'full kit' when you do buy to ensure that you have matching ropes throughout your entire set.
