The study of prehistoric textile production requires the excavation of sites with exceptional organic preservation. Here, the authors focus on thread production using evidence from two fourth-millennium BC pre-Alpine wetland sites: Arbon-Bleiche 3 in Switzerland and Bad Buchau-Torwiesen II in southern Germany. A comparison of the spindle whorls from these two settlements with a contemporaneous East-central European dataset suggests that multiple culture-historical groups with distinct technological signatures inhabited Neolithic Central Europe. Furthermore, the spatial distribution of conical spindle whorls within the pre-Alpine settlements suggests the immigration of both people and technology from the east, thereby illuminating the wider themes of mobility and innovation in prehistoric Europe
