This is a simple aid for drawing curves or circles from 1 to 10cm radius. The are no sizes on it because it is intended for use in simple notebooks or diaries where the actual measurements are irrelevant.

The centre can be visually positioned by using the hole through the Bush. A finger on the Compass Rest holds it in position so a pencil or pen can be put in the appropriate hole to draw a curve or circle.

If a particular size is needed then lines can be made on the page first and a suitable pencil hole chosen.
