So far so good!
Usually I purchase the 100% linen cushion covers from Adairs but they stopped selling the covers separately and I didn’t need new pillows so I took a punt on these. They are a linen/cotton blend and a thicker weave by comparison. My old Adairs cushion covers eventually wore thin from washing and use after 18 months so I hope these will last longer. I am happy with my purchase so far. The only annoyance is the hand-wash care instructions but I’ve taken a punt and washed in the machine. They seem fine. Will definitely buy again if they go the distance.
