At this time I have transfered my design to the other side/half of the buckle and I just finished engraving the main lines to the one side. I will next do the same to the other side then will start on the border pattern, leaving shading for last.
As you can see, the sanblasted design on the opposite half is still in tact and unaffected. Believe me, with my limited skills, I was all over that buckle when I engraved the one side. Had the design been transfered in a less permanent method, I know I would have wiped off most of it. I know others do this well, however, I'm not there yet.
