Using Pepakura isn't really that hard. All you need to know is how to print onto card, cut and fold along lines and stick edges together by numbers.
I have 2 updates today. First, I have finished pepping the back piece for my CP armour.

I hope tomorrow to get one of my parents to take a pic of me with the chest, back and helmet all on.
Second, I tested out the resin and fibreglass yesterday that I got. I had a couple of test pieces to use it on and so far I've learnt that I probably put a bit too much resin on with each layer, I need to leave it in the sun to get it to dry fastest, and I much prefer the thin fibreglass tissue then the fibreglass matt as while while the matt has much better strength it is also horrible to work with and harder to get into corners so I'll likely use the tissue on my helmet (probably doubling-up the layers too for added strength) and use the matt only for simpler bits like the chest. I'm hoping to start work on resining my CP helmet soon, but I'm out of latex gloves right now and I don't know if I'll get time next weekend to do anything.
