Kitchen shelving into Bud Vases

A kitchen renovation left a pile of old melamine shelving which inspired this collection of bud vases.  The shelving is 16mm laminated mdf (medium density fibreboard). It was a design challenge to create traditionally 3D objects from flat shelves! Test tubes are used to hold the flowers and these are removable for cleaning.
The designs are cut with a scroll saw and the cut edges painted.  I was curious to see if alcohol inks would take on the laminated surfaces.  I experimented with various techniques to obtain the different finishing effects.
