How do I remove a layout off my Facebook profile?

[Kylie<3]

I joined some sort of application (I think it was an application... I can't remember) on Facebook that allowed me to use premade layouts for my profile. Now, I can't remember what it was that I joined and I don't know how to remove it off my profile. Does anyone know how to remove a layout off of Facebook?

Hide Only Your Profile
Step1Sign on to the Facebook home page with your email address and password (see Resources below).
Step2Click on "My Privacy" to change who can see your profile. The My Privacy page lets you adjust each feature of your Facebook account separately. If you only want to hide certain features, like the mini-feed or photos, then adjust only those preferences.
Step3Click on "Edit Settings" for the limited profile. You will land on a page with a preview of your current limited profile.
Step4Choose all or none of the Facebook features you want people to see on your limited profile. To completely hide your profile, make sure all boxes are unchecked before hitting the "Save" button.
Step5Add people to the limited profile list from the My Privacy page. People you put on the list can only view the features you let them see. They will still be your friends, however.
Hide Yourself Completely on Facebook
Step1Head to the "My Privacy" page while logged in to Facebook.
Step2Search for users to add to the "Block People' list. You can add any user on Facebook. Once added, that user will not be able to view any part of your profile or find you when doing searches. This is the best way to hide completely from someone.
Step3Find the user you want to block and simply click "Block Person" next to his or her name.
Step4Click "Remove" next to the person's name if you later decide you don't want to block the person. If the person was your friend on Facebook, you will have to request to be his or her friend again
