Is it possible to cover a cake dummy in royal icing? And if so, any tips and/or trick?

I'm all out of fondant as is the town I live in. We have our bridal show this Saturday. I have 5 dummies done but wanted to do one more all in white. Any and all help would be appreciated!

Thanks

I just use my regular buttercream ... no vanilla, no dream whip. It hardens like concrete, easy to smooth, lasts forever. Kids love it when I tell them, "Sure! You can touch the cake! Go ahead!"

I dont' use RI for anything cake.

Thanks for this forum! I wanted to know when you ice a dummy cake with the buttercream as you described Indydebi are you still able to smooth it with a viva towel or Melvira's technique with the roller?

Thanks again for the assistance and guidance

Thank you! Thank you! I'm excited to give it a try
