We're a first time vendor going to CookieCon next month and need to choose which products to bring. Since we're from the cake world, which of our products [you can see them by clicking the 'SugarVeil' cake photo in the column on the right, or by clicking here] would be best to bring for cookie decorators? The AirPen? The Vacuum Pickup Tool? SugarVeil Icing? Mats? Thank you in advance for your help - really appreciate it! Hope to see you there.
