I did a quick google on camo poles.... came up with a lot but nothing concrete to give you a technique. Do you have any photos?
In general - for 1/35th poles you can look to rod styrene, streatched sprue, stiff solder wire, the inside wire from a coax (cable tv wire - preferably not the one to the TV in the living room). For thinner wire you can use old guitar strings, hobby wire (holds its shape well).
