"The Sewing Circle" takes a canonical look at the meshing of the resource limited 'New United States' with the extant economy of war torn central Germany. Four American teenagers set themselves the goal of launching a new industry, waging an uphill battle against adult skepticism as well as the intrinsic difficulty of the project itself. Armed with a father who has become part of Grantville's Finance Subcommittee the one girl has a dinner conversation involving ""Federal Reserve Fairies"", who magically make more money and regulate the economy.
