I've made a few Christmas cards to give me a head start on the busy season, plus a card I made for my niece to celebrate her wedding earlier this month.  The flowers I've made using a 'new-to-me' material called Foamiran.  It's lovely stuff to use and the finished flowers are quite realistic.  After watching a few Russian YouTube tutorials I got the general gist of how to shape the foam and was pleased with the results.
