I needed to replace some window sash cords on my property and having seen your company featured on Countryfile visited your website.
I purchased the Sutton 6mm rope as it had the breaking points shown. However, I would have chosen the braid, if more information had been provided. I was concerned about whether it would stretch in use and how strong it was.
If you are able to provide this and other details such as how the wool compares with other natural products, which are used, such as flax and jute, then Sash Cords could be an additional market for you to explore.
I have now fitted one set of cords, and wish you all the best for finding new uses for wool
