Thanks ID. Read the thread you attached and you are right a good starting point. I have some soft cotton rope that I have been using, fairly small core, but as I am used to climbing ropes I was hoping for something a little more substatial. Mostly I want the knots to look better and for the whole look to be more defined.
I was hoping to find a good online supplier if anyone has used someone and found theie service good let me know.
