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. 

Once I had my flowers made I picked out a piece of DSP to use for a top mat of each card. 

For this first card the flower pieces were cut from Blackberry Bliss CS, and Whisper White CS that I stamped with Blackberry Bliss Ink using one of the texture stamps from the Touches of Texture Stamp Set (the dots).  I cut the layered leaf pieces from Garden Green CS.  The mat was cut from a sheet of the Lily Impressions DSP. The sentiment is from the Amazing You Stamp Set, it was stamped with Garden Green Ink on a scrap of Whisper White CS and cut using one of the dies from the Stitched Label Die Set.  I threaded some White Organza Ribbon thru the holes cut with the die, popped the sentiment up with Dimensionals, and taped the ribbon to the back of the DSP.  The flower on the left was also popped up with Dimensionals.  Lastly I added a few Pearls to the flower centers and top mat.  

For this card the bottom mat was cut from Mango Melody CS and the top mat was cut from Mango Melody DSP.  The flower pieces were cut from Mango Melody CS, and Whisper White CS that I stamped with Mango Melody Ink using the same stamp as listed above. The top left flower was popped up with Dimensionals. The leaf pieces were cut from Whisper White CS and attached directly to the top mat.. The sentiment is from the Peaceful Moments Stamp Set and was stamped with Mango Melody Ink on Whisper White CS, and cut using one of the Stitched Label Dies, it was popped up with Dimensionals. I added Pearls to the center of the flowers and to the top mat.
