A soft, opaque, chalky look without being powdery like chalk.
With beautiful pastel colors and earth tones that give a matte look, this is a perfect ink for stamping techniques, processing with mask stencils and for direct use on paper. They are available in large format, dew drops and inkers.

How to:
Tip: for stamp with acrylic paint, use a piece of felt as a stamp pad.
Apply a drop of paint on a pallet, place a piece of felt (1mm) on top of it and stamp the paint into the felt (the paint should comes through the felt). When your stamp is loaded with paint, you can stamp on all kinds of materials such as clay, paper, wood etc.
