Made by a knitter, for knitters
I kept frogging sweaters that didn't fit. So I built this. Sizing based on M. Müller & Sohn tailoring — borrowed from tailors who've been solving fit for a century.

What knitters say
“First sweater where my wide hips and narrower shoulders were actually accounted for. Not boxy, not tight — just right for once.”
— Anna K., Netherlands
“It suggested drop shoulders for my sloping shoulders. I didn't even know that was a thing. The explanation made total sense.”
— Petra M., Austria
“Finally I understand why a pattern fits or doesn't. The shaping explanations are genuinely useful.”
— Claire B., UK
