Using the Shrink Ruler is simple! Follow these steps:

• Measure the final dimensions of your piece with a standard ruler.

• Locate this measurement on the Shrink Ruler, using the scale that matches your clay's shrinkage rate. (your clay supplier will normally provide shrinkage % on the packaging or on their website)

• Shape or mark your wet clay according to the Shrink Ruler's measurement.

• After firing, your piece will shrink to the intended size.
