Reinforcing jute twine

As I've not been able to garden for 2 weeks now due to worsening sciatica symptoms, I've been looking for short standing jobs when I go on my daily walks round the allotment site. 

The jute twine that's securing the trellis roof to my bean tunnel had started fraying so I've reinforced it with thicker and better twine. I only did 5 minutes/two posts at a time as it can be hard on the neck. It's reassuring to see that it's still fairly strong - who knows, I might get another 2 years out of it!
