Another approach to making Rondells is to put a drafting compass The type that has a pen on one end) in the center of where you want your circle to be. Put paint into the pen portion and draw your out line for the circle. Then simply paint the inside portion with a brush. Put heavy cardstock or balsa under the pointy end of the compass so as not to puncture the covering. You can buy Model Masters (or other brands) enamels or acrylics in the colors you need and your all set! Regards BobH.
