I have always had problems smoothing the top of a sheet cake. The surface is so large that my "tools" that I use always end up with a crease or a line where I have smoothed. Do you just have to use the same pressure each "swipe" you make??

Get it as smooth as you can then use the melvira roller method (found in the articles on the home page). I also use the viva method with a fondant smoother after I use the roller. sugarshack also has DVD that is excellent "Perfecting the Art of Buttercream". Her website is http://www.sugaredproductions.com/buttercreamdvd.html HTH

I use a large plastic bowl scraper and go over the top very lightly to get rid of any "creases" or lines.

thanks guys.. I'll give the Melvira method a try on the sheet cake. I use it on my other cakes.. don't know why I didn't think of that.. DUH!!

definitely do the "melvira method" you can look at my photos I get a ton of sheetcake orders and they're all VERY smooth thanks to that technique, don't know how I lived without it~!
