This is an aerial view of what I like to call my paint desk. All my art supplies are ready and set for me to paint. I keep my micron pens in a little travel bag. Fresh water is very important when I paint. It needs to be clear so I change often. If the water gets muddy, trust me, your paintings will be muddy too.
My most favorite paints are a boxed set of Pelikan paints. They travel well and are easy to work with.
I bought this Ikea -Alex flat file rolling drawers which is home to prints, some original work and paper.
One of my sons assembled it when he was home and it did take him a few hours but it works well and was reasonably priced. It is very heavy before it is assembled but comes with wheels which make it easy to move around my studio.
Here is the Pelikan set all shiny and new. It comes as a water color set or as an opaque set. I really love it. If I need larger quantities of paint then tubes are also available. You should be able to find them on line or at a nearby art supply shop. Most art supply stores are happy to order for you if you do not see.
