Today was messing about in woods experimenting.Ivy on trees is to thick and brittle ,but I messed about n braided 2 peices off ivy that was creeping on the woodland floor ,it’s much thinner .No processing nothing it makes extremely good cordage and I made 8ft length in less than 5 minutes.No twisting only braiding it will work as it’s stiff I reckon it might have been used as fishing line in the past v interesting .
