Paper Mache on a balloon?

Yes after you dip the strips of paper in the mixture (you should slid the paper through your finger tips to brush off excess paste) you simply place the strips onto the balloon (it's best to put all the pieces going in one direction for the first layer and then in a crisscross direction on the next layer to make a stronger product alternating each layer.). You should place several layers of paper to give it enough strength (5 or more if you want a strong product, at least 3). Make sure one layer dries before adding another one to prevent mold from forming. Also your flour and waster mixture should have a few tablespoons salt (yes tablespoons not teaspoons) to prevent molding. You leave a hole around the bottom where the balloon ties, you can grab the tie of the balloon when you think it's dry enough and tug it a bit to see if the paper mache is solid enough to stay in formation. If you've added enough layers and if it's dried enough it will stay in formation.
