Yarn > by Brand > Regia/Schachenmayr > Regia Potpourri Color Potpourri Color in 6 cheerful color combinations, you can start with much verve into the new season! The coloring not only fits perfectly with children's socks, it also looks great on grown up people’s foot. Potpourri Color does not have a color repeat, so there are no limits to fantasy. Four single plies are twisted together to create the ideal weight and durability for hand-knit socks. Like all REGIA yarns, it won’t felt and offers long-lasting wear and great shape retention. Machine washable up to 40° C (100° F) and can be machine dried.
