Quilting room re-vamp

I've not been feeling too satisfied with my quilting room layout lately.  I feel that it needs to be re-vamped and make better use of the space.  It's a descent size but maybe I have too much stuff!!  So woke this morning wanting to re-organise it all.  I have wheels for the Gammill and that makes it easy to move around but it also makes it too high for me to work on comfortably.  So how to do it???

Think first I need to tidy and put loose stuff away and then take another look?
