Very nice pattern
I’ve already made three, in different fabric. I love the model and it fits me perfectly.

modèle facile et très bien coupé
J'ai cousu cette marinière dans un jersey épais et peu extensible ( véritable jersey marinière français). Le résultat est superbe : très belle encolure et aisance parfaite , ni trop moulant ni trop large.
