Diane's Thin Line pastels are similar in texture to the Terrages pastels. They are made with extremely fine pumice in the pastel binder and pigment mixture; so that each stroke of pastel will literally bite into your paper. They are not gritty; they are very smooth and velvety- just made with a different pastel base. These sticks are thinner and are just a touch longer than the other pastel lines by Diane. If you haven't tried Diane's Handmade pastels here's an easy way to get started. Please note that Diane's pastels vary slightly in color and size from shipment to shipment, due to the fact that they are handmade!
