I recently attended a techniques evening at Glazed Creation where we tackled a 'cobblestone technique'. The results were really disappointing as very little cobblestoning took place! It transpired there were two issues, firstly we hadn't put enough of the cobblestone fluid on and secondly we had added to much colour over the top stopping the cracking from happening.
So last week I had another go and it worked! This tile will go around my glass mat with all my others (my aim is to cover my desk completely with tiles using different styles and techniques) I am now thinking about other things I can use this technique on as it is definitely one of my favourites.
