I then taken in consultation with the seller (Stylish décor) and was told that this sometimes can occur when new, darker linen (impregnation). After 2 -3 washes this should be gone.
Did the Council followed and washed the sheets twice - effect zero. Even after that (Ariel color and Lenor fabric softener) sheets is different from the surface characteristics. In most places it is still very hard to become a little softer in a few places - in any case, so that one can not speak of a cuddly soft fine Flannel duvet.
The color is washed twice already slightly faded.
"Stylish decoration" then offered to me to send back the sheets and they will claim these from the supplier as manufacturing defects.
Everything worked out - linen return - Money back. Many Thanks!
