I was wanting to do the same shape as the one on the site and have a good idea on how to do it but I"m not quite sure if that is how you do it. I'm needing it for a police officer's hat cake on Sat. the 18th. Also, any ideas on how to make navy blue out of royal blue?

Bumping myself up. I need help.

Not sure about the cake but here is something on the color.
NAVY BLUE =Royal Blue and Black

Thanks a bunch!
