There are two types of people: those whose hands are very often cold and those who are lucky.
Poor circulation, genes, whatever the reason- when your hands are cold, and have been since 5pm or last Saturday or 1993, it’s nice to hold something warm.
I love mugs without handles because I can wrap my fingers around them for maximum benefit.
These were handmade by my friend Ingrid. She insisted I use them, not just set them on my shelf. So I do use them, and I just love them. I even put them in our (mini-)dishwasher.
