Same here as the pp mentioned. I get crumbs in my icing if I don't. But I do not own the icer tip(on my list to buy), which I guess works awesome for icing the cake and not having crumbs in the icing! Jen
I don't crumb coat, but I do use the icing tip. I found that if I don't use the tip I am more likely to get crumbs but with the icing tip it's thick enough that I don't have to really worry about crumbs. But this is a personal preference. I think the majority crumb coat.
I started using the icing tip about a month ago and havent crumb coated since. I thought the tip would be more time consuming but for me it has actually turned out to be a time saver! I love it!!! As of yet I havent had any crumb problems. I also like the icing tip because I know Ive got an even thickness of icing on the cake (I always used to worry about that!).
