Fabulous pattern and such a pretty blouse. It is my first pattern from Atelier-Scammit and I love it. The instructions are clear and I used the auto translate and watched the video. I struggled with using elastic to do the gathers so reverted to normal gathering. I’ve just started Diapason blouse number two and the fabric for number three is already washed and waiting!

Drafting is great, instructions can be difficult to navigate
The drafting of this pattern is really well done. I normally have to make adjustments for my narrow shoulders but Atelier Scämmit top patterns fit me very well out of the box. Love all the different details. As I’m not the biggest fan of gathering I really like the idea of using elastic. I only find the 2-page instructions a little difficult to navigate on my iPad and would appreciate having the centimeters included in the English version of the pattern (now I constantly need to go back and forth between the two versions).

The prettiest blouse!
I love this pattern. I made it in a pretty block-print voile and it is so lovely. The fit is perfect. I changed the cuff a bit, instead of the elasticized version, I made a narrow (1/4") cuff. I also didn't do the elasticized ruffle as per the instructions, but did a conventional gathering stitch. I wore the blouse just yesterday and felt great in it. I will make another one for sure!

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.
