The pack arrived in the expected time. 
I didn’t  think much of it when I’ve unpacked them. They looked quite “sad”
So, I decided to get them ironed and they were transformed. It looked beautiful and hang better than the other pair we bought elsewhere and paid almost £200 for them. 
Furthermore, it really did the job as we expected the room to be warmer with the new curtains and we immediately felt a noticeable difference in the temperature in the room. 
I strongly recommend these curtains.
