When I need thicker stems like for long stemmed gum paste roses, magnolias and the like I take 18 gauge fabric coated wire and begin to wrap it. I then add another wire and wrap those together. Then I add a third and then wrap all three together. I have a purse cake with a single red rose in my pictures if you want to see what it looks like with this method.
