Start with the flower center. I'm using yellow wrapped with orange:
For the petals--a little more fancy...two (count 'em, TWO) colors of purple:
Reduce to a little bit smaller than the center cane (this can vary, depending on how many petals you want...smaller for more, larger for less); cut the number of petals you want, the same length as the flower center:
Place the five (more? less?) petal pieces around the center cane and lightly compress. There are two options at this point. You can have a flower without packing. It's a little tricky to reduce...a matter of pulling the cane rather than compressing and rolling. Or you can pack the cane with a background color and roll it to reduce.
To pack the cane, form small background triangles to put between each petal:
Then wrap a sheet of background color around the result:
Reduce as desired (and wrap with another color if you like). Ta-da! A flower cane!
