Favorite uses for lavender?

So I um… accidentally bought 2 POUNDS of organic lavender buds. I thought it was 2 oz. ANYWAYS I have sooo much lavender now, and I need more ideas on how to use it!

(I also got 2.5 oz of blue cornflower, which is still more than I expected it would be but is not an unwieldy amount. I’ll happy take any advice for uses for that as well)
