Here is a card I made for a technique group I am on. The technique in the background is called crinkled chalk. Its pretty easy - you just crinkle up some plastic wrap, pounce it in a chalk ink pad and then tap it on your cardstock.
The flower stamps are by Impression Obsession. They are a clear set of petals, circles, leaves and stems. I really like the patterns on the petals but I'm still trying to work out how to use them effectively. They are large and I'm still trying to come up with layout ideas.
For the focal flower on this card, I stamped one pattern in pink, then over stamped another pattern in burgundy and embossed the burgundy with Ranger holographic powder. Its much more sparkly IRL.
By the way, the matte behind the Just a Note is actually a scalloped square, set as a diamond with the top and bottom points cut off.
