I'll be at the BAMM AGM this Saturday with a table at the Mosaic Market so come and say hello if you're attending. I'll be there with details of the workshops etc plus a load of sample bags for the 4 mm marble and the riven cut. 
Guilia Vogrig is giving a demonstration on using the hammer and hardie as part of the program but I'll also have my set there so if you want to have a go find my table.
