When you mount your Pun Fun stamp set you could carefully cut inbetween the words and the picture with a craft blade and then mount the words onto the end of the wooden block. (Please be very careful how you cut, as you won't get a replacement if you cut the image.)
I have copied this card here from the catalogue. I may have to add some white words in place of the arrows. I'll have a think on that!
I love the way that the buttons match the colours so nicely.
