We purchase blocks of acrylic from a U.S. Supplier
From here we slice them, draw patterns on them and cut out the "roughs".
We will start with this slice.
From here on, its lots of sanding and shaping, and we have a sand paper drawer with lots of it.
This is how we obtain our "rough shape" and it is quite chalky at this point and details are vague if there at all.
Then it is curved.
After 3 more steps of sanding, plus 3 steps of polishing we finally get some details.
