SugarVeil® 2-pack of 3.4 oz SugarVeil Confectionery Icing

Does sugar veil set up stiff enough to stand a butterfly up in a cup cake? Also how difficult is it to cut through if it's wrapped around a cake?

Does this work for sugar cookies- want to stamp it for cookies?

Can you use this on the sides of whipcream cakes?

Will this 2-pack be enough to cover thirty(30), 3.5 inch diameter cupcakes?
