just a couple questions

[Omegazero]

Does the quality of the container that moths mate in affect the quality of the moths?

is the quality of the tree of the tree you cut down limited to the quality of your axe?

Do loom construction signs ever appear or when they are all gone they are gone forever?

[tristamizumi]

No.

No.

Construction signs for anything only appear when you or someone else places one down and puts one or more required items into them. So if you want construction signs for looms to "appear" get the skills to make one, place one, and put a stick/string/board/whatever into it.
