Dear Sir,
I am fairly skilled in poison making. I'd be more then happy to help you, what sort of venom sacs are we talking of here though? Such things I need to know if I am able to tell you if I have the skill to make them something more useful. If it is Ettencap Silk Glands, for something other then poison, then you would do better to seak out a tailor, as they do can do more with them then make poison. Hope you find the help you seek.
