[Updating my usual Spring Festival post]
In addition to the regular Spring Festival items, you can get some items useful for level-cap characters. Anfalas Star-lit Crystals cost 60 Spring Leaves and are Bind on Acquire, so they must be bartered by the character that will use them. Essence Reclamation Scrolls cost 90 Spring Leaves and are not bound, so can be sold, passed or traded, e.g., by a lower level character.
The two-year cycle for Premium dyes available during festivals continues. These are the dye colours that cannot be crafted and are only available for festival token barter or Mithril Coin purchase during festivals. Each festival has 2 colours for festival barter and 2 colours for MC. In alternating years, the festival barter colours are available for MC and vice versa. The market for the dyes is thin and hard to predict, and some colours are more popular than others, but I have sold thousands over the past two years and made a ridiculous amount of gold. Of course, if you think you might use them, now is the time to stock up.
For the Spring Festival, you can barter 15 Spring Leaves for either 6 Dark Purple Dyes or 6 Lavender Dyes. You can pay 10 Mithril Coins for either 6 Bullroarer's Green Dyes or 6 Shire-Plum Dyes.
As usual, I recommend the Ale Association and Inn League delivery quests as a way to generate festival barter tokens. If you do all 11 deliveries for both factions, you can earn 66 Spring Leaves in a well-planned hour. See my blog post for details:

I plan to run it a number of times to get tokens for star-lits and premium dyes, and am happy to take others along. Let me know if you're interested.
There is a daily quest from Sergeant Tom at the Bree Festival Grounds (he is also a festival barterer) that rewards an additional 3 Spring Leaves for doing 10 festival quests. You must get the quest before completing any of the individual quests for them to count. In addition to the Hedge Maze quests and the new quests by the Bree Fairgrounds stage, there are quests in Duillond (including Shrew-stomping) that count towards the daily 10. (Inn League and Ale Association quests don't count.)
There is also a 3-tier, 4-days per tier wrapper quests, which reward Figments of Splendour and Scraps of a Reclamation Scroll.
