Okay, I lied! It was messy, but I did get it to work.......
Here you see one arm finished. Just for grins, I am showing the process of getting there on the second arm. I start by greasing up the torso and adding a blob of putty inside the arm. This is just pushed on with the finger and squished onto the body, then the putty is squished around the upper arm.
The same is done for the lower arm. The idea here is to get the basic shape and bulk of the sleeve in place. Notice that the bulk of the sleeve disappears to almost nothing at the elbow and the shoulder since the body would be pushing against the fabric in these areas.
Now that I have the basic shape of the sleeve worked out, I can start adding wrinkles. These are simply pushed into the fabric with the toothpick tools. With the tool moist and a little rolling action, the folds can be made fairly smooth. Then it is just a matter of working and reworking until you get the surface and the folds just right......
Like this. See? That wasn't so hard!
In fact it was kinda soft and squishy - until toward the end when things started to stiffen up. Once the putty gets to that state, then the fine details like seams can be pushed in with the x-acto knife. The "puckers" caused by the stitching are then lightly pushed in with the end of a not quite sharp toothpick.
It might be hard to tell now, but there has been quite a bit of bulk added to the arm between this photo and the last one. Such adjustments are frequently necessary to get a decent balance between one arm and the next. Fake it till you make it, that's how I do it.
Here I have added the collar with putty. The gas mask canister slings are made from sheet lead from a wine bottle. The ends are simply pushed into the collar while it is still a little soft. Boy, that didn't go too well! The strap looks a little wonky right now where it goes around the neck, but the end parts are copascetic. That was the major object. It is just another job to go back and remove the bad parts and redo them with putty.
As can be seen, we are on the finishing stretch now. All that is left is that wretched strap at the collar and some miscellaneous buckles and doodads to make him complete. But that will be next week.....
Cheers!!
