The haloscreen bundle will get you more green, so if you're doing a summer ghillie I'd get that. Just make sure you get the "starter pack" as it's enough material to do a full ghillie. The laser cut stuff is a rip off. The nov set is more material for less, but half of the sheets are quite brown. I prefer cotton for brown as it ends up looking more like dried leaves. Saying that it's not a bad deal tbh. There's also AGM on empire airsoft, which I believe the large pack gets you more material than the halo starter pack, but it's still about the same price as the haloscreen. The small pack wont be enough for a full ghillie, but you could comfortably to a viper hood plus a gun wrap with it.
I also seriously recommend Nutscene's dyed raffia. I'll link 'pesto' which is excellent for grass, but you can also use 'twill' and 'cinnamon' for replicating sticks. And 'olivine' I haven't seen before but that looks like it could be a really good colour too.
