These tickets are an example of how:
In both these projects I have stamped the image with Memento and coloured it with Promarkers (you don't need to be too fussy with your colouring either). The best bit is that to finish you colour the whole area with Satin or Pastel Beige marker which dulls the colours for a vintage look and also blends them.
The sentiment on the second example hasn't stamped very well because I have mislaid all of my acrylic blocks (d'oh!) so I used my finger and pressed a bit hard! It should read "For You".
