I'm saving up for a good rig from WB, but while I'm wating I wanna make a DIY rig for myself and a buddy. I live in Denmark so I think that http://www.extremtextil.de is a good place to shop. The question now is. What fabrics should I use??

I weigh 230 lb or 105 kg. I'm 185 cm as is my buddy.

I wanna make a simple gathert end hammock hopefully in single layer.

Can anyone point me in the right direction please?
The best thing would be a fabric that is curenty in stock and ready to ship :-)
