I noticed that there was a striking lack of horned cats in my cases, so I made one! Yule cat here bears a set of lovely curling horns, a few srouts of charming whiskers, and some flames coming off one eye so you know e's really alert.
The wonder of a copper mask is in the strength and give of the material. The ones with the big horns, like this, are balanced carefully, with the horns running along the top of your head so that their (still slight) weight rests on the top of the head rather than on the face.Because it is so strong, the mask can be very thin- this makes it both very light, and makes it possible to fit as a second skin. They won't block your peripheral vision the way a leather, paper maiche, or plastic mask would. They can be very comfortably worn all day and night- no worries about sweat or rain causing them to soften and lose their shape. Rinse it with clean water at the end of the night before putting it away. They can stand up to anything you throw at them. As for packing? Throw it in your bag. If you're checking the bag, stuff a balled up pair of socks or a spare shirt where your forehead would go. Easy.
Not planning to wear your mask? They won't mind. They can hang flat against a wall, or sit on a shelf. Even the folks who buy them to wear them have them on display most of the year, and I promise that they love it.
