I made a template and hand cut these cookies, using a photo of an actual gumball machine as my model. (The template was approximately 2 1/4" wide x 5" high.) The gumballs are mini-M&M's. I was going to do all the gumballs in icing, then decided I would go insane long before all the cookies were finished! Simple sugar cookie with glace icing. Outlined with thickened icing, using a #1s tip. I used a #4 for the white area, #2's for most others. Edited to add: I will post the template for these cookies ASAP.
