I bought one last year (after Easter, on special) for the school library, and it's since graced the table outside my office full of face-up borrow-me impulse-grabbing books. It's had various things hung on it over that time - bats at Halloween, laminated fabric motifs, book cover and so forth, depending on our themes (with banners/bookmarks). In fashion parlance, its 'cost-per-wear' has been worth the purchase; it provides a focal point on a table I deliberately keep a tad untidy, so kids don't feel, by browsing, that they're disturbing a neat-and-do-not-touch display.
Bed Bath N Table, the shop from which it came, has three white tree options this Easter. None are dirt cheap, but I'd point out that one of the attractions of these is their scale/size - they don't get dwarfed in the context of a library. The above tree is $99. About the same height, but 3D/in the round is this one:
I don't think I have a spot for it in my library, but it certainly has potential. Smaller, but not small, is this one at $129:
As I said in my original piece, these aren't specifically Easter - you can tweak the themes to suit yourself. They do only seem to be on sale (in these larger sizes) at Easter. So you can buy now and secure one, or wait till the after-Easter discounts and potentially miss out (last year I gambled and won, but it's always a gamble!).
Bed Bath N Table is a chain of shops, but unfortunately they don't have a website/online store. The shops can order stock in from other shops, though.
No affils or suspect brown paper bags with apple pies or crisp banknotes: we've been happy with ours, and so I thought I'd give you a heads-up, when I saw them again. Photos taken with permission.
