I have been so brave - I wall papered one wall in my bed room in my little flat. I got the wall paper for something silly like £1 a roll when Focus were selling up - but not had the nerve to have a go. It's years since I did any wall papering. I did paste the wall instead of the paper and it helped make the job a lot less fiddly and messy.
It looks really super - not sure I want to do loads of it though
