The following cards were made similarly.   I began by making the flowers.  I cut a solid flower piece out of cardstock.  Then I cut two segmented flower pieces, one from the same color cardstock and one from a coordinating color, giving me what I will call an outline piece and then the individual petal pieces.  

I glued the outline piece to the solid flower piece of the same cardstock color and then glued all of the petals in place.  I cut additional solid flowers and segmented flowers and combined the pieces as above.  I cut coordinating flower center pieces and attached them as shown.  

These 3 cards were inspired by one I saw on Pinterest made by Debbie Danford.

For this first card the bottom mat was cut from Poppy Parade CS, the top mat was cut from Whisper White CS.  The flowers were cut from Poppy Parade CS, and Whisper White CS that was stamped with the dotted texture stamp from the Touches of Texture Stamp Set.   The leaves were cut from Mossy Meadow CS and shaded with some Mossy Meadow Ink for contrast. Next I stamped the top mat as shown with a dotted texture stamp from the Label Me Bold Stamp Set using Poppy Parade Ink (1st and 2nd generation stamping).  The sentiment is from the Peaceful Moments Stamp Set and was stamped on the top mat using  Poppy Parade Ink. The larger flower was popped up with Dimensionals.  Lastly I added a White Perfect Accents Shape to the center of the flower and some Red Rhinestones to the top mat.

  The bottom mat for this one was cut from Mint Macaron CS, the top mat from Whisper White CS that was sponged and dotted (as above) with Mint Macaron Ink.  The flowers were cut from Rich Razzleberry CS and Whisper White CS dotted (as above) with  Rich Razzleberry Ink.  The leaves were cut from Mint Macaron CS and sponged with Mint Macaron Ink.  The same sentiment was used and stamped directly on the top mat with Rich Razzleberry Ink.  The larger flower was popped up with Dimensionals.  Lastly the Enamel Shapes were added.

The bottom mat for this last card was cut from Pretty Peacock CS, the top mat from Whisper White CS dotted with Pretty Peacock Ink as in the cards above.  The flowers were cut from Pretty Peacock and Whisper White CS.  The leaves were cut from Whisper White CS and sponged with Pretty Peacock Ink. The same sentiment was used and stamped on the top mat with Pretty Peacock Ink.  The flower was popped up with Dimensionals and then some Pretty Peacock Faceted Dots were added.
