Worn linen sheets and clothing were used for wrapping and padding mummies. Linens that weren't actually used for mummification were sometimes buried in embalming caches, like one discovered in the Valley of the Kings (KV 54) that dates to the burial of Tutankhamun. Three mended and laundered head cloths (09.184.217–.219) found in Tutankhamun's embalming cache were originally identified as kerchiefs worn by guests at the king's funerary meal. We now believe that they were part of the leftover embalming linen. This blue kerchief, dyed with indigo, is quite small and may have belonged to Tutankhamun when he was a child. Whether it was worn by Tutankhamun or not, examples of dyed linen from ancient Egyptian times are extremely rare, making this a very precious object.
