Hiding a note or notes
When a note is hidden, it is not rendered on your desktop. It still exists, but it is invisible. Hidden notes can be recovered using the Show command.
You can hide a single sticky note by choose "Hide" from the sticky’s context menu. To display the sticky’s context menu, right-click note.
You can also hide all your stickies at once. From the StickyNote main menu, choose "Hide" from the "Stickies" menu.
