I just tried the Melvira Method of smoothing buttercream using a high density foam roller. I'm so excited about how well it worked. I just wanted to post how smooth it made it. I would definitely recommend this method!

what is the melvira method? Just curious as I am always trying to get mine smoother.

It's pretty much just using a high density foam paintbrush roller. I finally got to try it today, and it is so fast and easy!
Here is a Link to the tutorial!

Where is everyone finding this item? Looked on Lowes website and all they show is the strip, not the roller. I already do the Viva method, wanna try out the Melvira!

You can purchase them at Wal-Mart. They are incredibly in expensive so you can buy lots of back up rollers!

I found mine at home depot with all of the other paint rollers. Hope you find one! This was so much easier and way faster than the viva paper towel method!

I've been using this method for over a year and I don't think I could do cakes without it! It works perfectly every time (well...except on the random finicky batches of buttercream)! I got my rollers at Lowes, in the paint roller section. It says high density right on the package. My Walmart doesn't carry them, unfortunately.
