So I'm going for an Alice in Wonderland type look right now and I really need some grass and a tree background, is there anything specific that I could be out on the look for?

Hi MercyGrim96, I am happy to help out!

These are some of the items that have trees in them:
Tapio Defender
Storybook Journey
Holiday Tree
Deep in the Jungle
Candypuff Trees

And these items have grass or green flooring:
Marvelous Moustache Bros
On the Farm

And these items have bushes and other greenery and plants:
Mene Life - A Visit to Britain
Bloomin' Lovely
Camping Adventures
Wedded Bliss Topiaries
At the bottom of the garden...
Monkey Business

Thank you! I will be on the look out for them!!

you are very welcome, MercyGrim96! let me know if you have any other items you are looking for <3

where do you find backgrounds for the avatars

Most of them are in CIs and are therefore expensive and can be rare. Some EIs have backgrounds. They'll be cheaper since they weren't paid for with real money. You can find some ooold backgrounds that go for under 1k! However, older backgrounds don't reach to the edges of the avvie image box thingie like the newer backgrounds do. If you want to locate specifics, try haunting this forum.

Or you could ask a user what the item's called if you see them wearing a background you like.

Amane beat me to it yet again! I want to help too :D
