I am travelling a bit back and forth between Nigeria and Norway, and when I am in Norway I am not necessary in my hometown and my home. So a couple of times I have been so cold, particular on the feets. So last time I was in Trondheim I bought a ready-to-knit set at the airport and knitted me slippers that travel easy.
Warm, woollen slippers that do not take up a lot of space in the suitcase. And they fit relatively well on the feet, so I am happy.
