Hollow Blocks are Micro Blocks which are hollow in the center of the block.
They can be crafted by placing Hollow Covers, Panels, Triple Covers, Slabs, Cover Slabs, and Triple Panels of the same material into the crafting grid in such a way that their combined thickness is at most equal to that of an Anticover (7/8ths of a full block). Jacketed Wire, Bluewire, or Cables can be placed inside them for an almost seamless wiring setup.
Hollow Blocks can be crafted using a large number of different combinations of other Hollow Blocks. Any combination of the Hollow Blocks below will work, provided they add up to at most 7/8, and all materials used are made of the same material.
