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.  

For this first card the bottom mat was cut from Blackberry Bliss CS, the top mat was cut from Whisper White CS.  Next I used the open die from the die set (see picture) to cut out pieces from the top mat letting the Blackberry Bliss CS show thru.  The flower was cut from Blackberry Bliss CS and Whisper White CS that was sponged with Blackberry Bliss Ink and then dotted with a texture stamp from the Touches of Texture Stamp Set using the same ink. The leaves were cut from Garden Green CS and then sponged with some Garden Green Ink for contrast.  The sentiment was stamped directly on the top mat with Garden Green Ink and is from the Amazing You Stamp Set. The flower was popped up with Dimensionals and lastly I added a Pearl and a few Enamel Dots to the card front.

The bottom mat for this next card was cut from a piece of the Lily Impressions DSP, the top mat from Whisper White CS. I used the same die as above from the featured set to cut the "patterned holes", letting the DSP show through.  The flower was cut from Calypso Coral and Petal Pink CS that was dotted using Calypso Coral Ink using the same texture stamp as above. The layered leaf pieces are also from the featured die set and were cut from Old Olive CS.  The flower was popped up with Dimensionals.  The sentiment is from the Positive Thoughts Stamp Set and was stamped directly on the top mat with Old Olive Ink.  Lastly I added some Glitter Enamel Shapes to the card front.

For this third card the bottom mat was cut from Blackberry Bliss CS, the top mat was cut from Whisper White CS, sponged with Granny Apple Green Ink and the "holes" cut out. The flower was made the same as the one in the first card above.  The leaves pieces were all cut from Granny Apple Green CS and shaded with Granny Apple Green Ink.  The sentiment is from the Amazing You Stamp Set and was stamped in Granny Apple Green Ink. This flower is also popped up with Dimensionals.
