This has been one of my favorites where an actual pineapple top was glued on, large champagne bottle was covered in tissue and covered with lots of truffes (86 to be exact) from German blogger, Bitavin. This version send the truffles higher to the top.
from German site, Echtlustig
This version left the tissue paper that comes on the truffle and the sticker and uses silks for the stem. If traveling, wrap it in plastic for no truffle loss from Conny Simon
This version uses Werther's Originals instead from flyinghousewive blog
Here is another example with gold tissue on each piece and tissue leaves from Mara-macabre
Here the stickers were kept on, and assorted textured paper used for the leaves from Paperblog
Here is a Youtube video where they used a beer bottle instead in case you need a little help!
