Nils worked with his father carving wooden figures of various common people in the Scandinavian flat-plane style of woodcarving.
Between Nils Trygg, his father and two brothers (Lars, and Carl Olaf), they carved over 10,000 figures.
He was proceeded in immigrating by his father Carl Johan who arrived in Halifax on 3 March 1928.
Trygg generally carved solo figures from basswood or pine, and mounted them on a base.
He had a stylized execution with clean cuts, working from a single piece of wood.
