Hi, sorry about the delay, I had to find the paperwork. Years ago I purchased Amann Serafil from Sewing Thread Specialists Group. They have a website, just do a Google search. Be aware , they have an Amann brochure, that you can download from the site but this supplier has a select amount of colours/sizes in their warehouse. Black (standing rigging) is easy and so is a beige colour (running rigging), it's getting the colours in various sizes that you need to check, especially if you want to go for a dark brown standing rigging. I use size 40 black for larger standing rigging, size 120 for smaller ropes like seizing/ratlines. With the beige colour , I use size 60 for running rigging, with size 120 for seizing etc. I do multiply threads to get thicker ropes. I also noticed that when I Googled, there is more available to Aus, than before. So try Google, Ebay. I have emailed the company I mentioned, to get an updated list of their Amann Serafil range. I'll let you know. Hope this helps. It's often frustrating getting things in Aus, quite often postage costs overseas make things a little expensive. I have so much satisfaction in making my own rope. I have modified my ropewalk many times. Enjoy, hope I have been helpful.
