On White Flower Cake Shoppe's Facebook page they say they are talking to Craftsy about doing a tutorial. Also on their page it said they use swiss meringue. I agree with costumeczar. I used regular buttercream, 1/2 butter 1/2 hi-ratio shortening and I think my flower came out OK for a first try. I would like to get my petals higher but I think that is going to come with practice and getting the right consistency icing whatever icing you may be using.
