Produced by silkworms that are fed only pure mulberry leaves, we uses grade A raw mulberry silk to make all of the Adult Collection bedding. The raw silk is hand-stretched and then sewn together to make a silk filling that will not bunch or shift inside the silk-filled throw blankets, comforters and pillows. The raw mulberry silk is also woven into a satin-finished charmeuse silk, which covers the blankets, pillows and covers and is used to make the crib sheet and pillow cover.
