If you're going to make flowers, well you're going to want to make leaves. They're pretty easy to make, although there are a couple of tricky parts that are hard to explain. Good thing I took pictures!
Roll a shortish, fatish log of green (or whatever color you want your leaves to be). Wrap with a darker color green (or whatever color, etc. etc.)
Stand the cane on its end and slice into four pieces as shown (a shorter, fatter cane makes this step easier)
The goal of the next step is to put the veining in the leaf...you want a contrasting color between each of the pieces you cut. The way I do it is to put three slices on the vein color and trim even with the cane pieces
Then reassemble the pieces
Here's the hard part to explain. You want to cut the cane on the diagonal...hopefully this picture shows what I mean
Put the vein color on one of the cut sides and trim to fit
Flip one of the pieces so the veins on one piece go a different direction than the other. Again, hopefully the pic shows what I mean.
Smooth the cane and reduce as desired. Ta da! A leaf cane!
