My kitchen needed color so I decided to add the color with the light panels.  The plastic panels I purchased at Home Depot for $6 each.  Next the paint, Michaels has glass paint that works well on the plastic panels.  I made a pattern on paper put it on the kitchen table they put the panel on top and started outline on the smooth side of the panel with black paint.  Once that is dry than start filling in the areas with the glass paint.  I did one panel a weekend and changed the colors of the butterflies on each panel.   You can find lots of patterns on the internet or the local library.  I tested the paints on a small mirror I purchased before taking on the kitchen.  Amazing what a little paint can do to brighten a drab brown kitchen.
