I like the look of cocnut for snow but I have customers that don't like it. Any suggestions?

You could get a block of white chocolate and grate it. The shavings could resemble coconut!

Edible glitter...and lots of it!.;0)

You can also use white/clear edible glitter that comes in larger pieces and really looks like fresh fallen snow.

On the Food Network Challenge from last year (Edible Ornaments) one of the decorators used a combination of powdered sugar, coconut, glitter, and lustre dust. Maybe you could try that without the coconut.

You could spread a thin layer of royal icing out, let it dry. Then use a pastry/bench scraper and scrape the royal icing. It will crumble and powder, you could mix in some edible glitter and luster dust to give it that bit of sparkle.

I like that idea Lorendabug

royal icing sprinkled with granulated sugar and a little glitter gives a very good snow effect

Just plain ole confectioner's sugar looks good, too!

What's it being used on? Powdered sugar would melt into anything wet. Though there is powdered sugar that doesn't melt.
I like the RI idea. Makes me want to put snow on something!

What about adding edible glitter to the RI idea? That will make it kind of sparkly too!
