Sign in to your Facebook Home page.
Click the "Create Group" link in the left column of the Home page. It's beneath your Facebook photo and any groups you already belong to. If you don't see it, click "More" to reveal additional options.
Type a title for your group in the "Group Name" box. Click the down arrow beside the box to choose an appropriate icon. For example, if your group revolves around a football team, choose the football icon.
Click in the "Members" box. Begin typing the name of the friend you wish to add. Facebook will automatically drop down a list of matching people. Click the name to add the person.
Click the drop-down "Privacy" menu to choose who can see your group and the group's information. Your options are "Secret," in which only members have access to group information; "Closed," in which group membership is publicly available but the posts remain private; and "Open," in which the group's membership roster and posts are viewable to everyone.
Click "Create" to set up your Facebook group.
