Handloom

Improving looms
''Vetical warp-weighted looms are primitive and impractical to use. With the increased experience of our weavers and our better woodworking tools, some propose to research an improved design of handlooms that would increase their productivity and comfort.''

Potential Requirements
-Bronze Working

-Having at least 4+ weaver's and cloth makers at level 2 fully staffed with good workforce seems to trigger it (Workforce usage requires resources for them to work with, simply having them work but produce nothing doesn't count.)
