Abstract
A sealable vacuum chamber has an outlet. A template within the chamber includes flow guides for guiding colorant under vacuum across and into porous material when in contact therewith toward the outlet to create a pattern in the porous material. The flow guides allow for at least slight variation in the pattern without being altered.
