To create a base where the parting area equals the roller diameter, which diameter size should be used?

• A. 1x
• B. 1½x
• C. 2x
• D. 2½x

Answer: (A)

The key idea is base width relative to the roller’s diameter. To have the parting area equal the roller diameter, you want the base width to match the rod’s diameter exactly. That means using a base size where the base width is the same as the roller’s diameter. If you choose a larger base size, the base would be wider than the roller, so the parting area would no longer align with the roller diameter, affecting how the curl forms. So, use the base size that makes the base width equal to the roller’s diameter.
