Have to share this great card with you. It is done with the marker technique.
Marker Technique: Color directly on the stamp with the markers. I like to start with the lightest colors first. After you are done with all the coloring, then you need to "huff" on the stamp to "remoisten" the ink from the markers. Then stamp it on your cardstock.
The white texture is the SQUARE LATTICE EMBOSSING FOLDER. This embossing folder has been cut out to have that smooth spot.
The stamp set is called WATERCOLOR TRIO. It is available in the clear mount or the wood mount.
