This section is all about "Sculpting the Edges". This is most easily done with a "Little Torch" style torch with fuel & oxygen to boost the heat, resulting in a very hot tight (pinpoint) flame where you can localize the heat to "burn" or melt back just the edge so it rolls into a thick organic edge.

If you don't have one, your options are to saw scallops then sculpt with abrasive wheels to mimic the look or try the controlled melting of the edges with the air Acetylene torch like demo in Work Around #2. (one of my students proved to me that this WAS possible. Thank You Laurel !!) This technique often results in your dusted areas being over fused and smoother than before, but there are always compromises. ( I think I dusted it AFTER melting back the edges in demo video)
