SRD:Minor Creation

You create a nonmagical, unattended object of nonliving, vegetable matter. The volume of the item created cannot exceed 1 cubic foot per caster level. You must succeed on an appropriate skill check to make a complex item.

Attempting to use any created object as a material component causes the spell to fail.

Material Component: A tiny piece of matter of the same sort of item you plan to create with minor creation.
