Manufacturing process of a felt strip for M31 German helmet liner.
If there is a cloth or synthetic fabric in your copy of the liner, change it to a good, proper felt!
In German balaclavas, felt was used as a soft padding, not cloth! Felt is pressed wool fibers, and broadcloth is a fabric. They look similar in appearance, but the difference in properties is significant.
The color of the felt varied from gray to brown.
The width of the strip is about 4 cm, the strip is bent (about 7 mm) and at the same time covers the inner rim of the liner (which itself is 35 mm) almost completely.
