"Not a creature was stirring, not even a mouse." The beloved poem, A Visit from St. Nicholas by Clement C. Moore, is full of Christmas imagery, and this line is a favorite.
Way back in 2009 we made a sleeping mouse button for Art to Heart's I Believe book. Now, at least a dozen batches later, the sleeping mouse button became the star of Not a Creature was Stirring. Shhh...he's sleeping.
