My IPHONE got a Christmas present

We have a real winter here and my IPhone does not like when it is too cold. The battery is flat in no time. So my IPhone got a Christmas present - a coat for going outside. I might attach a string to it, so that I do not have to carry it in my pocket - too close to my body. It will be like a little handbag. I might knit something similar for my glasses 😊
