Lovely pattern

Very straightforward pattern with good instructions and helpful video guides. I love the numerous variations and made the long sleeve version with frilled cuffs and the neck frill as a gift for a friend. I am going to make the same for myself. The French seams and bias bound neck seam make for a great finish. The only change I made was to construct the neck frill with gathering rather than the elastic method which I’m not familiar with.

Great pattern. Will make it again in another fabric. Comes up very snug fit so will add a little to both the length and the back. I would say it is an intermediate skill rather than beginner level.
