It’s a simple repair. It all depends on where you live. If you’re in North America, shipping packages to Europe—plus customs duties—isn't cost-effective.
Steve, thank you very much for the kind words. Rescuing items is my passion. Wherever I go, I’m always on the lookout for repair materials. Recently, while visiting Piotr from the forum, I spotted a scarecrow wearing a felt hat. Now I have material to repair more felt helmets.
I also have a pickelhaube cover made using the same technique, i.e., made entirely of cardboard, and the straps are made of ribbon, not leather. I have the impression that they were made for soldiers of lower rank.
Unfortunately, as a result of recent events and the customs war with the EU, all shipments to Poland are being sent back from the USA.Nothing can be done.
