The other colours were created with (1) Green 3 parts + red 1 part (2) Brown 1 part + green 2 parts + white 8 parts (3) Brown 1 part + white 4 parts
Splodge shapes on in layers using sugar syrup or cmc for glue – I do it from dark to light and make snake shapes and rough Y shapes. You don’t have to be to exact with glue but if it too much pops out the sides it will have to be dabbed dry.
Once pattern has been created bearing in mind the size required for what the camouflage is to be used for (large splodges for a cake or smaller splodges for cookies) flip it over and roll it in both directions. Rolling it will increase the size of the shapes but will meld them together.
Flip it over and cut/use as required.
My cookies had edible image printed of the body combat logo, these were attached with edible glue. Bear in mind you can only have logos/licensed characters printed if you are the license holder for the image, or the item is being made for the company who is the license holder of the image.
