I think you are right about small places. My friend and I, lacking a good climbing tree, were forever building forts, clubhouses, flower houses (between the real house and a big cypress with flowers stuck in the bark.) I'd still like a treehouse.--hart

Growing up in the upper peninsula of Michigan, I was completely and utterly in love with the Dandelion Cottage and would beg my parents to seek it out every time we were in Marquette.
I dream of the day when my workspace is stationary - at the moment, as a grad student, I am constantly mobile, moving from coffee shop to library to (even) the grocery store. Still, there is something about being in a state of work flow, knowing which spaces work for me as a writer that is just amazing. And, yes, the grocery store has wireless. We live in wonderful times indeed.

I have many memories of my younger brother and I appropriating any space we could find and turning it into an impregnable fortress we were prepared to fight to the death to defend against hordes of imaginary pirates, monsters, and zombies. The battles were epic and quite often resulted in the destruction of the space, which of course lead us on a journey to find another. Having that space to claim as our own was a staple of my childhood. I would have loved the tent set up you have created as an eleven year old.

The Guardian (UK) website has a historic collection of 116 writer's rooms.
"Jane Austen described her writing as being done with a fine brush on a 'little bit (not two inches wide) of ivory'. Her novels are not miniatures, but she did work on a surface not so much bigger than those two imagined inches of ivory"
