I have tried using parchment cornets repeatedly but have the following problems: 1. the hole snipped is not round and doesn't pipe a round stream of icing, even very small tips and even if I unflatten them with my fingers. I love doing icing dots and the distortion is especially bad there. 2. the paper tip of the cone becomes damp quickly and looses its rigidity. Have any of you cornet users solved these issues? You must have because the work is BEAUTIFUL!
