Scroll down to bottom for english. Making particles for a speckled sheet of PC. (Ana Belchí) She made a skinner blend then sliced off a portion of the bottom. Cooked for a very short time 20 sec (maybe 10 more) and crumpled up the clay. Sprinkled it on the skinner blend for a great effect. She also did the circle replacement on this sheet.
After making the skinner blends, I stacked them on top of each other alternating the lights and darks. Next, I played a bit with circles and lines. I actually didn't like the effect much, so after making the pieces, I covered them with black embossing powder before baking
