I posted this on the "How do I" forums but thought it would fit here as well if not better.
I see decorators using a small flexible trowel for applying icing to a stencil on a cake in the videos, but I am having a hard time finding a source. It is a polystyrene trowel.
Does anyone have a better tool for that or a source to buy one of them?

bought mine in the paint dept of Home Depot. For patching holes in walls.
It works great!

I'll look at my local Home Depot to see what I can find - thanks

I just use a bench scraper.

I do mainly cookies and I love using palette knives. Most have nice flexible tips which I love.

You can get a set of various sizes at Michaels for a very reasonable price.

They are in the artist painting isle.

Great suggestions!

I'm such a nerd. I use my Pampered Chef stoneware scraper. My sister sells Pampered Chef, so they're pretty easy for me to get ahold of.

I have one of those and thought of it but worried it might be too stiff?
I read that a for sale sign cut to size from Home Depot might do the trick too...
