I need some help, and maybe some tips. My little brother lives with my husband, daughter, and I, and in about 5 weeks were having his 10th b-day party which is Army themed(my husband is in the Army and my lil bro looks up to him) well, I am making an Army helmet cake, using the bake n fill betty crocker pan, and on the helmet I want to make it camoflauge. I want to do this using icing, not fondant, and was wondering if it is even possible? does anyone have any tips? Please help me! Thank you!!! 
Check the galleries for camoflauge cakes -- they have many different ones done in a variety of mediums. And post your pix when you are done -- we want to see how it turns out! Welcome to CC! 
sure...it's just a matter of mixing up several colors and then piping them onto the cake in a camo pattern ... irregular splotches of color that touch each other --
I'd use a photo of hunter's clothing to get camo pattern.
pipe using any tip you feel comfortable using, just being sure to each area solidly filled. then use a spatula (the little offset pointy one works great) dipped in hot water to smooth while still fresh (can also use a finger dipped in cornstarch -- but for large areas this is much less successful)
can also once crusted, smooth further w/ viva paper towel or the marvelous Melvira foam roller method.
(calling JanH to supply links to those methods!)

Definitely possible =) Definitely check out the galleries and if there is one you really like send a PM to that person and see how they did it.
From my understanding using buttercream about the best way I have read how to do it is use a larger round tip and pipe areas of colors around the cake. Make sure they are touching. Then take parchment paper and either a fondant smoother or the light touch of your hand and gently run it over the parchment paper to smooth out the icing underneath. You will definitely need to make sure it is a crusting buttercream to do this though =)

If you find one you like that's been done the way you'd like to try you can PM the person and ask for directions.
My best guess at camoflage, off the top of my head, would be to pipe the different colors in different shapes and then use the viva method to smooth them together. But as I said that's a guess, most people are happy to share if you ask.
Good luck 
I agree with the above suggestions. I did a camo cake for my son last year in buttercream (sorry, forgot to take pics) I used a large round tip to pipe irregular shapes in the different colors, then carefully spread with the offset spatula to make them meet. Then you can smooth with Viva. Good luck, can't wait to see the pic!
Go with doug's suggestion.> That is exactly what I did and it worked great. I would give a picture, but my computer ate the pictures...then deleted them 
Have a great day and good luck,

I can't post it right now, but I did a camoflauge helicopter on a cake and what I did was the small stars method (think Wilton) and put three different colors green in the bag. End result was a very cool camo helicopter. I'll post it a little later.
Good Luck! thank you guys sooo much for all your tips and advice, i greatly appreciate it! I should have no problems making my cake(well hopefully) thanks to you guys!
