It was a hobbit-nail, and that means comfort. But perhaps some difficulty typing. Nail art maestro Kayleigh O'Connor added Bag End to her thumb along with some pleasant greenery from the Shire. She writes:
I've never tried anything on this scale before. It's a solid, 3D nail which is supposed to resemble a little Hobbit-hole. It's about an inch long and an inch high, made using clay, fake grass stuff and acrylic paints/nail varnishes.
O'Connor also made an impressive set of Gandalf nails.
