Trending at the moment is the chalkboard technique. It can be simple & bold or subtle & forgiving.

This first one was done by simply stamping & embossing on black cardstock. I outlined the edges with white gel pen before embossing the main flower on cardstock, sponged the centre, cut it out and popped it up. Using a paper towel, I swiped some white chalk lightly here and there.

This second one (also called popping pastels) is more forgiving in the way you don't need to mask. It is a little more time consuming but worth the result. I stamped the main flower first dabbing (not rubbing) the chalk all over, picking up chalk again after a couple of dabs. It is important to stamp them one at a time. You want the chalk to stick to the ink. Although the ink stays wet for a little while, the sooner you apply the chalk the better the result.
I continued with the other flowers before moving onto the leaves. Here is where it's forgiving. I was able to stamp over the flowers and sponge the green chalk over the top. Depending on if you want the leaves infront or behind the flowers you can sponge the flower colour over the part of the leaves you want behind. Clever huh.
I didn't emboss the sentiment on this one. I just stamped in white, and slightly offset and stamped again for the shadow. Again swiping gently with white chalk ink.
