Shellwork → The word is formed from "shell" (from Old English *scealu*, meaning a hard outer covering) and "work" (from Old English *weorc*, meaning something done or a deed). Shellwork refers to decorative work made from shells or resembling shells, combining the idea of a hard outer covering with the act of creating or crafting.
Think of a 'hard outer covering' ('shell') being used in a 'crafting' process ('work') — that's why shellwork refers to decorative items made from shells.
