Isaiah 45:3

In the famous lace shops of Brussels, there are special rooms devoted to the spinning of the world's finest lace, all with the most delicate patterns.

The rooms are kept completely dark, except for the light that falls directly on the developing pattern, from one very small window. Only one person sits in each small room, where the narrow rays of light fall upon the threads he is weaving, for lace is always more beautifully and delicately woven when the weaver himself is in the dark, with only his work in the light.
