The Art and Hobby shop over here tends to have Christmas items most of the year - because if you are a crafter for Christmas, you probably are making things a lot earlier than if you were buying them.
The Christmas Shop in Brown Thomas (our luxury Dept store) was open last week, but hadn't been 10 days before. I did hear grumbles. But I longed for some of the lights! (They used to open that section in late July, last year it was mid August so it is slipping back again in line with "Christmas creep" grumbling - but I think it's nice).
The National Museum and the 2 major Irish crafts stores near Trinity College (selling things like Newbridge Silver and Waterford crystal to lots of US visitors in particular) have Christmas items mixed in with their general stock all year as well, but they do get a lot more festive in autumn (well the 2 stores do, I think the museum keeps to just a handful of nice things that are quite different).
Otherwise, not a lot to see here yet....
...there's less than 4 months to go, how are we going to be ready in time...don't panic MNers, don't panic....
