New to hammocking in a camping sense...

And I'm realising that one of the first things I'll need is to stay warm. Anyway, I'm looking at making my own UQ. Right now I'm planning on an Insultex 3 layer with ripstop on both sides. I may use shockcord and barrel locks but haven't decided on that yet.

My main question is: what do I use for thread? I've found DIYgearsupply and they have two threads in supply: http://diygearsupply.com/product-category/thread/

Also, if anyone has suggestions for other insulation materials, I'm not opposed to learning more. I've read a bit about Primaloft and a little about wool (does anyone use wool blankets for UQ, TQ?), and down seems great but I don't know if I can afford it.

anyway, thanks for the consideration.
