Then, being careful to "contain" the circle in your fingertips (it might fall out!) gently turn the sheet over again, so that the original score is face up.

Next, make "relief" scores in the four corners of your square sheet. Rotate the sheet flat on the table, without lifting it, to position it for making the relief scores. The sheet weakens with each score, and could break apart at any time.

Each score is made away from the circle toward the edge of sheet.

Then, run each relief score using a method or tool with which you are comfortable.

Sometimes two relief scores in each corner help release the tension better.

As the relief scores are run, the sheet edges should fall easily away from the circle.

Circle edges will be clean and smooth,
