Using blankets so far: too hot for a bag! heavy Habotai is the heaviest grade you can get I am told. I'm sure the hammock would work for about a year or so with more reinforcement but I do not have the kind of money you would need to replace that amount of silk and the amount of reinforcement adds to the total weight meaning that the reason for using silk in the first place is lost.
Cotton is heavier, but has strong fibres. Also I wouldn't mind trying hemp fabric as that is very strong if I could find a source: I understand both fabrics do not require a huge amount of effort to repair, (to repair silk in the field would require significant work because it frays very easily and therefore it is not just a case of sewing across the hole, you have to reinforce the stitches and stagger the stitching).
For those interested, I think I will try cotton or hemp next. I have already decided to opt for a thick thermoplastic flysheet because it is 100% recyclable, is harder to tear, gives some rigidity to the structure so the eyelets will not pop out easily, and does not catch fire as fast as thermoset, (thermoset will burn quickly and drip boiling hot plastic on you, the thermoplastic will melt first, and then catch fire and then drip burning plastic on you, but does not "go up" so quickly!). Then I will need some form of mozzi netting that I am going to attach to one side of the shelter, the other side being enclosed using a sleeping bag zip, (this should (I hope) allow me to have the snake skin thingies that hennesy use). As I want room in the shelter I have used a simple pulley system to allow me to raise and lower the distance between the flysheet and mozzi net and I am working on a way to be able to lower the flysheet from inside the hammock so that I don't have to get out in the case of "almost horizontal rain"; I might have to abandon this as it is a tad complicated. Finally, I want a number of water proof bags that hang over the hammock so that I can keep my muddy boots out of the hammock and off the ground at the same time (or is it just me that has that problem?).
I guess this is similar to a hennesey with heavier material and no velcro strip, which I do not like (just personal taste), and therefore the zip is needed to get in/out of the hammock. I also have bought foam to use as an insulation sheet that will clip together inside the hammock to form good insulation and stop it sliding out from under you. Hopefully this will not make the whole thing too bulky.
