Can anyone recommend me some items that are somewhat earthy themed?

you can probably find some nice flower and plant themed items in esther's shop

many of the recently revamped spells galore items are wearable; you can see previews of them in this thread: Spells Galore Revamps - Previews

some esther items from earlier years that aren't in the shop anymore:

other misc items i find earthy or naturey:

Thanks!

You should take a look in Sarah's quest shop. You can find some lovely items there.

A lot of items in the 'Spells Galore' shop can be used as backgrounds/foregrounds as well, just hover over to see the preview.
