I don’t have any double sided paper so I picked two complementary patterns, glued them together and then cut out my circle. The fun thing is that each circle you cut makes two trees. I made two nearly identical cards so that each pattern could be the primary one.
I used Wausau flecked cardstock for the base and sentiment. DCWV Christmas pack papers for the tree, Sizzix Sparkle 2 thincut for the star, EK tree border punch. Sentiment from computer in Alleycat ICG.
