Trousers are the hardest garment to get right, and the most satisfying when you do.
You’ll learn to recognise what affects the fit, understand how to fix it, and create your perfect trouser block, the one that fits how you move, sit, and live.
No formulas. No copying. No guessing. A playful, intelligent approach that gives you total design freedom.
Finally understand how trousers fit your body and never struggle again.
Every woman’s body is different and this course celebrates this.
One custom block, endless trousers designs
Understand the logic behind the trouser block and draft your first version step by step.
Test & correct fit using our library of visual adjustments for every body shape.
Once your block fits perfectly, turn it into any design you want: from tailored ones to jeans.
You’ve tried to make trousers before, but they never fit quite right.
You want a practical, visual system instead of confusing formulas.
You love the idea of creating your block not adjusting someone else’s.
You’re ready to experiment and finally make trousers that truly fit.

"Courses are wonderfully organised, breaking down complex sewing projects into manageable, step-by-step videos. I love how I can work at my own pace and can always go back to some lessons if I need to.
But my favourite thing is how Liza 'normalises' mistakes and shows how to fix them. This approach has been a game-changer for me. It made a huge difference in my sewing journey. Also, whether you want it or not, you start becoming much more creative."
