My only issue is why a vest with a net on it is worth over 100 quid and how you'd apply the strands to one.

Loop the strands onto the net

Key points to decide on first are what it will be used for and how?
Are you going to be laid down, crawling etc, moving quickly and then ducking down into position? - That can mean you only need your head, back and arms as mentioned but also what you use for the base material (e.g. Smock) and whether you need extra padding (if going on hands and knees then you definately need pads)
For extra pads you can sew internal pockets in the knees/elbows to add and remove pads, or permanently sew the pads in
I had a few issue sniper pads that were rubber pads in sheets of dpm material, but have also made them with old foam mouse mats. Exercise mats can also be cut up
add rubber loops or thin bungee cord loops of you intend to customise with vegetation or temporary hessian for colour schemes, more or less bush etc
abuse it - you don't want a nice neat ghillie that looks like a ghillie
consider a ghillie bag. It's a bit obvious when you see a ghillie at the start of the game or running across the field. you may have a flip open bag and drag a ghillie panel over you once you are at a chosen spot
beware of fire. What if a smoke grenade goes off near you? Make sure you are not covered in something that will just ignite in seconds
