I recently bought Iris Mishly's latest rose cane tutorials and finally had a chance to have a go at one.
You get 7 different rose tutorials and I can highly recommend them! Check them out here: http://www.polypediaonline.com/

I think the end result looks pretty good. I lost a bit of my background but this was probably due to me mixing some premo frost with kato translucent. I really like how transparent premo frost is but it is a little too soft for canes.
