The YouTube channel Pointy Hat recently had their 100,000 sub special on the Feywild. They created a short adventure (1-2 sessions, obo 3-4 hours each) set in the Feywild. The video it's attached to is kind of long (~40 min) but is an excellent look at the Feywild. The actual portion covering the adventure gives tips on running it as well. I've read it over and it's pretty well put together.
