Lots of good info!
Very similar to the CRAFTSY class I just took on cookie decorating.
I'm not fond of royal icing though - I love using Sugar Baby Frosting. Did you originally provide this recipe Barbara?
Sugar Baby Frosting
1 32 oz. pkg. confectioners’ sugar, sifted
1/3 cup evaporated skimmed milk
1/3 cup white corn syrup
1 teaspoon pure vanilla
1/3 cup water, boiling
Combine milk, syrup and vanilla in a saucepan over heat and add boiling water.
Blend together with electric mixer. Add confectioners sugar and continue mixing
until smooth. The frosting consistency is similar to a glaze. Color with powdered food coloring for decorating cookies.
