I don’t know if I’m missing something… I’ve looked in the ‘house party’ section and done a search for ‘winter festival’ decorations. I can’t find them anywhere. The only holiday decorations I could find was the candy bowl for halloween. Is anyone else having this problem?
UPDATE: I’ve created a bug report. If you are having the same issue, please like to let the developers know.
The holiday items situation absolutely shocks me. Apparently the winter holiday items cannot be obtained anymore and can only be used in save games where you unlocked the items. 
I was concerned about that as a possibility in December and decided to play all my existing save games to unlock those items while I could.
I thought the plan was that when the calendar system was introduced that holiday items could be obtained during the winter festivals/holidays, but this doesn’t seem to be the case. 
Hello @RestlessSloth @Starwing they are still there. Go to “Social Event” and scroll down to “Winter Festival Supplies” (checked just now)
I don’t doubt that they’re available in the Build Studio, but, just like the premium vacuum cleaner and anything else you haven’t unlocked, those items will disappear from the lot as soon as you place it in your game. It gives a message that items not owned aren’t applied, or something similar to that.
I haven’t tried building with them in the Build Studio and then add the creation to the game, but I have played new games where the items are not available in the build mode within the game, and there’s no way to unlock the winter festival items for new save games as far as I can find. Things like the bonsai tree stand, premium vacuum cleaner, a special computer, and other items can only be unlocked through gameplay.
I checked again and they are still there even in gameplay mode. Can you send a screenshot of your build mode > furniture > social event section? If it’s not showing for you it might be a bug.
I wonder if it’s a bug. I might make a bug report and see what they say…
I remember a friend of mine said the items were supposed to be unlocked and I just thought he was mistaken. It must be a bug that some of us have.
Here’s a screenshot from the Build Mode in the game when I went to a different family than the one who unlocked everything. I haven’t tested by creating a brand new game since the March update because I’m very busy getting this save and two others ready for a new gameplay series.
Hey guys, turns out @Starwing and @RestlessSloth are right. These seasonal object do show up in build mode when you are inside a save but only for public properties and business properties. They do not appear on private properties since those are tied to specific families and families have to unlock.
I had been working on a public property to upload to canvas and that was where I was testing this, so it was showing up for me because of that.
Hopefully we get the full calendar update soon, since Kjun said the calendar update will come with year long unlocked season event furniture and all that.
I’m sad.
The items exist in the game and there is no good reason to deny access to the items after the calendar was introduced. It doesn’t matter if they plan to add another thing later, they should not have restricted the items to the specific households that unlocked them during the winter holiday event.
I agree. Any unlocked items should be linked to a player’s account not an individual save file, especially during early access. But I’ve noticed a few inconsistencies between build mode in-game and the build studio, so it might not be intentional and will hopefully be fixed soon
