How much is too much?

I have been thinking a lot about my work space lately.  I am very lucky to have a big room with lots of natural light at one end.  It has a sink and fridge and even a bathroom:  so I can loose myself down here for hours (if not days).  

Previously I have had lots of things around me.  Apart from the sewing machines and light box next to my computer & printer: all of which have to be out and at the ready, I also have lots of beads, threads, fabrics, magazines, books, shells and seed pods, etc etc etc on display.  In the past I have found all of these things helpful in providing ideas and inspiration, but lately I find it all a bit overwhelming.

I am gradually putting most things away in cupboards and only leave out things I "need".  Of course with Christmas on the way it is the season for clutter!!!!!  I wonder how others deal with their workspaces.
