In my last post I mentioned making faux cake postcards and I'm finally getting around to blogging them! They are made from pink rigid foam (like the kind you nail up in basements for insulation), spackle, paper and paint.
First you cut the insulation into a wedge shape and glue a piece of paper to one large, flat side. Then paint the other large side the color you want your cake.
Then spackle the top and wide edge with "frosting". You can tint the spackle with paint if you want, or add glitter "sprinkles"! When it's dry you'll need to seal it. I use spray-on finish spray.The paper side will be what you write on and place your stamp on. I've successfully mailed this for around $1.50.
