This plugin adds a “Stick this to the front page” checkbox on the admin add/edit entry page of selected custom post types.
Set options to enable in Settings → Reading. Unless you’re using custom queries to display your sticky posts, you probably want to check the option to add selected post types to the blog home.
Note: Sticky custom posts are stored in the global ‘sticky_posts’ option field, just like regular posts.
