Starting with the furthest part in perspective of the picture
( i.e. the sky) and working forward.

I use a brass brush on my angle grinder and "sketch " the picture by grinding in various directions.

I then move onto the wave part, to give more texture I use the brass wheel, then a steel wheel, then the actual grinding wheel and a dremel (mini grinder).

I just go to my local hardware and they only sell these two...a brass and a steel...I think they are used for removing rust etc...LOL though I have heard a lot of people use the 3M roloc system???
