Make someone a sweet Valentine’s Day gift by covering a pen. Creative in Chicago makes a simple marble pattern by twisting and marbling traditional Valentine’s Day colours and slicing the results like a cane. This makes a confetti pattern which is a pleasant sort of abstract design and makes it easy on clay beginners.
As the tutorial suggests, the best pens to use for this are the cheap stick ones with the solid white barrels. Old style Bics are great and I’ve had luck with some of the dollar store ones.
