It took me a long time to make this card but I like the result.
First of all you have to create a window. (When it was finished I made a template so I could use that the next time.) Next the paper is stamped with a Hero Arts stamp (Designer Woodgrain Wood Mounted Stamp). The little stars on the background are made with a punch. (I don't have the Silhouette Craft Cutter, you can see it in the link, but this is also an easy way.)
The butterflies are stamped twice, one time on normal paper and coloured with distress ink, the second time on acetate with white Staz-on.
The idea is from Shari Carroll (http://heroarts.com/blogs/club/2011/08/17/making-a-scene-with-silhouette/).
