I have been reading an article in Writing Magazine (April 2012) about the author Karen Maitland. She writes wonderful mediaeval thrillers. She says that when she is working she becomes "immersed in mediaeval life". This is why, I think, her books have such a great atmosphere with all the details of what life was like in those early centuries.
But what really fascinated me is that Karen has a dolls house, a mediaeval great Hall "complete with glowing fire and mad monk." She says that whenever she peers inside it is as if she is right back in the mediaeval world.
What a wonderful way to incorporate your dolls house into your working life!
