Easy to apply it says on the packet. And it was. Once I got the pieces off the backing sheet.
It stuck to me, it stuck to itself, it stuck to the backing sheet. In the end I had to cut it off my hand and try and work out how it went together again. In its favour, it is strong so it didn't tear even though I was trying to rip it apart.
It's a cheap, easily-removed piece of prettiness, though, sadly, a little lopsided and not properly centred on the wall.
