While you say you are using stiff consistency, you may need to make it even stiffer for the base of the rose if you want it to stand without leaning. You might also want to shorten the height of the base just a little (1/8 in. or less). Finally, make sure the bottom of your base is thicker than the top – it should be a cone shape with the narrower end up. If you are still having problems with the base standing, allow it to “crust” – let it stand at room temperature, uncovered, for about 1 hour until the icing surface dries a bit – this should help with stability.
Your petals might have a feathery edge for two reasons. First, your pressure isn’t hard enough – try squeezing the decorating bag harder. If you still are getting that feathery look, you may need to thin the icing a bit (Sorry, I know I just told you the base needs to be very stiff!).
