I write with this little room in utter chaos as a BT engineer is due to arrive at the end of the week to upgrade our Broadband. I live in hope but not expectation of great things. My room is packed to the smallest corners with very useful bits and pieces which in no way can be thrown away and in the midst of this is the cabling for the computer, so I will leave the picture to your imagination. Its rather like an archaeological dig, going back in time with all the levels of 'experiments'. I even found a half finished 'knot garden' and marvelled at my tiny stitches.
If you would like to know how to tie a square knot properly, something which I think I have done incorrectly for years, and also why you should make the effort to get it right – then follow this link and if you are like me spend quite a bit of time until you get the satisfaction of getting it perfect. You will feel so proud of yourself! The whole site is worth a look and you can listen to Susan Mills book artist talk about her work.
