These are made using the awesome Flowering Fields suite.  I used the dies in the Tulip Fields bundle to make the windmill and all the tulips at the bottom.  They are attached to a 5 1/4 x 4 piece of white cardstock that has been colored with a blending brush. I used pear pizzaz and balmy blue for the background colors.

The photo below shows the stamps and a windmill stamped in espresso on so saffron cardstock.  With the designer series paper in the suite.
