What tip do you recommend to do a grass border? the wilton book says use 233...I don't have that one, is there another one I can use? I am going to do a grass border around the bottom of the cake. Thanks for any help!

Tip 233 is what I use for grass. It works well because of the multiple openings. I don't know of another tip that would make realistic looking grass that wouldn't take forever. Sorry If it helps, tip 233 is readily available at any store that sells Wilton products (Michael's, JoAnns's, Hobby Lobby, etc.) if you have any of those in your area...unlike some of the other tips that can only be ordered online.
