Rose

To make the rose I drew out the shape of one side of a rose using the create line tool, with 5 vertices. A lathe modifier was added to fill out the shape of the petals on that side. This was then copied and rotated around a central point moving about an eighth of the way each time, until the circle was completed.
A cylinder was added for the stem. The rose head and the stem were grouped together, copied twice and positioned to make a rose bush.
