Swallowtail

 

I cased these cards from Marelle Taylor's website.  The stamp is called Swallowtail and is a large stamp and is great for colouring.

 I have used Cajun Craze and Tempting Turquoise as base colours for these cards and I have coloured them in using the SU pastels (no retired) although markers or daubers would also do the trick.
