I cut masks out of foam, adhesive and use floral paint spray-?

I make masks for our community theatre once and a while and although I'm not an artist I'd like to spray finer detail and I've always used pieces of cardboard to direct the spray in certain direction. The foam is EZM or Easy foam. Is there a way to direct the spray better? I'm only making ears now an I use the floral paint because it stays soft and doesn't melt the foam.One more thing I need website that has pics of animals (ears).I cut masks out of foam, adhesive and use floral paint spray-?
I would use colored markers
