Picture of Flower and Voronoi coaster

I designed and made my coasters.

I used Inkscape for designing and laser cutter for manufacturing. I will show you how to draw the patterns of flower and Voronoi by using simple circles and rectangles, and extension in Inkscape. It is easy process including basic functions in Inkscape, so would be good practice for beginners!

Step 1: Flower coaster: Draw rectangles and circles

To draw a flower, start with drawing rectangles and circles.

1. Draw a rectangle which width is 3mm, height is 150mm.

2. Duplicate the rectangle and rotate 30 degrees (Object> Transform> Rotate). Repeat till you have six rectangles like a circle.

3. Draw a circle which diameter is 30mm. Place it between two rectangles where the circle touches the edges of the rectangles.

4. Select "Snap an item's rotation centre" (Object> Transform> tool bar on the right side). Select the circle and the cross mark appears in the centre of the circle. Drag the cross mark to the centre of the rectangles. It allows you to duplicate the circles with the same distance from the centre of the rectangles.

5. Duplicate the circle and rotate it 30 degrees (Transform> Rotate). Repeat till you have 12 circles.
