Hi Fiona
I am also from Scotland so if you let me know the area I might be able to help you find the things you need. You can read my story at this site

I know of a number of places where you can purchase macrobiotic items both online and off!
http://www.clearspring.co.uk/ is an excellent UK supplier, you'll find most things you need here pickle press included.
