@zeetrollplays reading your input to the genetic material sac post!
I’m more inclined to stick with the idea of a weaved pitcher with which to catch the material mainly because it has a sort of narrative to it; a silk ‘pail’ is a clear predecessor to a metallic (or plastic?) one, and certainly makes the pail seem like a more natural progression. Which is sort of what I was going for!
An internal coating process definitely has its own merits, but lacks the continuity I had in mind when spiders were going through my head.
