They are the sort of thing that is better made than bought. For if I remember they were not the greatest quality and maybe a little thin. If you want me to source the materials (ie. bungie cord) I will, and we can re-use the white plastic toggles.
If you bring them with you to Wetton I will sort them from there. Also as my job is now not tied to the school holidays I should be able to get to Dent earlier this year and give you a hand.
