Maybe not a lot of people will understand me on this but I will give it a try.
Most people think of scallop shells as those that have the scallop ridges.
Sea Scallops don’t have those ridges and are a LOT bigger. They are what I call “flat”. They are really not flat, but they don’t have the ridges.
OK - hopefully you follow that. If not I will find some pictures
Question is ---- Has anyone tried to cut and/or engrave scallop shells or something similar.
