This is a really useful thread with lots of links on what you can do. For making string you can make a DIY rig or you can use a drill with a hook and something to tie thread around. I haven’t built a rig yet as I’m just playing around with ideas at the moment but I love making string so will probsbly get too it soon.
All you need to use embroidery thread to make the string. Standard polyester thread is a good starting point as its cheap and easily available and then its about finding what works.
