I have multiple domains, specifically:
janaygreen.com
latinogreetingcards.com

Right now, my shop for janaygreen.com is in the root directory.

To organize, I want to have my shop for janaygreen.com in a folder called "janaygreen".
I want to have latinogreetingcards.com in a folder called "latinogreetingcards".

How can I put my shops in the folders above without the home url being:
"janaygreen.com/janaygreen" and "latinogreetingcards.com/latinogreetingcards"?

I want the home urls to be:
"janaygreen.com" and "latinogreetingcards.com"

I greatly appreciate any help in this matter.
