well i took that much time because i had 8 courses in that semester. besides i used to travel a lot and other problems.
material…well it was pro course, and i get to learn from an italian artist (prof).
we actually commissioned the work for a hospital…so the money we got from that hospital actually bought things for mosaic.
all the mosaic work tools were provided by the teacher.
i will post the details of tool and material asap 
o really…or wo kon si cheezain hain jo main nay khrab ker de hain?
ps. samad it was my first mosaic. it is easy for guys to chisel but it is not for us gals. i know europe is way ahead in these things…so why dont u post ur work?
