You transform Raw Material into something physical, limited by your powers and mental capacity. Talk with your DM about what you wish to transform the Raw Material into, and if that is capable for your character.

This Raw Material can be transformed into Floating Fabric(see Floating Fabric in Chapter 1). 

If the Raw Material transformation is subjected to magic like Dispel Magic or Counterspell, the transformation unravels into unprepared Raw Material again. 

If you wish, the spell may include a prayer or offering to Gaia that serves as a keyword. When that word or action is done, the Raw Material unravels into prepared  Raw Material.
