I created a CAS card for my mass production this year.  In fact I made 50 of them.  I used a Memory Box two step die cut, one for the trees and a shiny paper for the outline of the trees.  I love the way they came out. Was a bit tricky gluing the thin outline to the patterned paper trees.  A bit of glitter glue, a Stampin’Up sentiment for the front and inside and they were ready for mailing.  Love it!
