Here is another creation from from the online class I did with Heather Summers (see here for details). It's called an interlocking card.
I used Kraft, Vanilla and Rich Razzleberry cardstock. The Kraft cardstock and the bird has been stamped with the flowers from the Vintage Vogue Stamp Set. I used the Polka Dot Embossing Folder for the centre mat.
The trickiest part of doing these cards is making sure the squares all fit together.
