Sometimes you just want to give a 'small something' just to let a good friend or colleague know you care. A 'little something' that's more than a card but not quite a grand gesture is perfect for a 'congratulations' on your new job, 'well done' on that hard essay or 'thanks for feeding the cat'...... you know, just that 'token gift' that can be easily posted!
HINT: why not do away with the card and simply attach a label with your sentiment written on, much more personal xx xx
