So I have this cookie cutter... http://www.annclark.com/product/213/traditional-cookie-cutters
I'm trying to think of a way to do them! Should I just do the 5 colors in little bags...at a bit thicker than normal flow...and then fill with white in the center? I'm having a hard time visualizing...
Or should I flood the whole thing white and then go with the rings (but I'm thinking that might be hard unless the icing is thicker for the rings- so it doesn't flow into a big ole color blob!)
Suggestions?!
Okay now I'm thinking that since I have so many different colors to do..outline the outer edge and the inner circle with white...then fill with each color? Then fill the center with white?
Ladies! I know you've got something for me!!
I'd do it in fondant, but then that's my cookie decorating method of choice! 
You could lay down a white base in royal icing or fondant, then let dry and do red and blue fondant rings.
I would do the whole cookie in the white RMBC then outline all the colors with RI.
I agree with Bobwonderbuns. Just what I was thinking when I read your question. If you are a royal fan then definitely flood base with white then cut your circles from mmf or fondant or rbc (whatever you like the best). This way your rings will be perfect. I don't know about you but piping circles in royal never works out for me. They are always off a bit and with these circles they really need to be perfect. Good luck and don't forget to post. Great cutter BTW!
