There were some quests last year for Thanksgiving/Christmas which caught people out who didn't have large resources in stock. The timings were not good also and what with random drops from quests and "holiday" items which stopped dropping after Thanksgiving which confused people like me in the UK who thought "holiday" applied to Christmas. There were lots of unfinished Pergolas and Kingdom Inns. The Christmas trees, some you bought with coins, some with gems but you were supposed to buy them to chop them down before Christmas.
It was very odd .....there were lots of complaints during this time but I think TL learned a lot and subsequent events have been reasonable to achieve.
Since then a lot of people have become hoarders of resources. I don't think you can plan because we don't know what they will have in store for us this year but it makes sense to keep your resources as close to maximum as possible.
I would suggest only doing trades in the exchange when you are close to maxing out unless it is the eggs and milk which are very quick to replenish if you need them. I would also suggest keeping all your crops close to 99. If an update began with "give 75 carrots" there will be many players who will do it instantly. If you have to grow those carrots, you may end up a couple of days behind. Silver and fur are very often required and not easy to obtain if you need them quick. It is always a good idea to have plenty of inks of different colours and also max stocks on all your petals and some stocks of your basics like beams, blocks, glues. Keep your saps stock high too just in case you need to make some more. In fact it may be easy just to check every item you have in your inventory which is low and aim to get it higher if you can, lol.
As far as food is concerned aim for stocks of the basics sugar, flours and chocolates in case of new recipes which need them and have a few feasts for each of the adventures we currently have, just in case you need to send then knights out on them.
And don't forget we have been given opportunities to get and make faerie blocks, beams and pastes. Do not be surprised to see if we need them soon.
