I like stowage on my Flames of War tanks. For me it help gives them that 'no, I have not just come out of the factory' feel. The organic softer shapes of rolled up tarps and so on helps break up and contrast against all the straight lines of tanks. However getting a hold of 15mm stowage is not cheap so I sometimes get the urge to make my own. I use Milliput. It is a 2 part modeling putty.
After cutting off two pieces roughly the same size then after rolling, stretching and folding it together I start by making small sausage shapes. I put them on my table and often give them a squash to give them a little flatness on top. First step with a finished example near by above.
I have created some longer rolls for my Shermans and Crusaders from a Mid-War North Africa force. These tanks are the core of my collection to emulate a small part of the British 9th Brigade that was under New Zealand command for the El Alamein battle (Operation Supercharge specifically). Images show them having very large and long rolls fixed to the sides of tanks. Prior to the massive loses they had in any case.
me to show the sculpting better. The large one on the Sherman is yet to have the straps painted with a different colour.
Cheers from Brendon (The Kiwi) and happy modeling.
