In stock


Mon 7 – Thurs 10 August (4 days)
10am – 4pm

We’re all different shapes and sizes. Thankfully. But when it comes to making clothes from a commercial pattern, this can sometimes make things tricky. Learn a unique, tried and tested method for getting a great fit every time. Create a fitting pattern, based on your body shape, and use it for your future sewing projects.

This is Cassandra’s most in-depth Fitting Masterclass to date: she’s going to take four days to equip you with a tried and tested method for getting great fit every time. You’ll come away with a paper pattern, adjusted to your body, that you can use time and time again on your own projects. As always, the workshop is hands-on and student focused. People of all genders, sizes, and backgrounds are welcome and encouraged to attend this course.


You will learn a unique fitting method, utilising horizontal and vertical balance lines to visually draw the eye to recognised fitting issues. The method is iterative, starting with adjustments to the paper pattern and the construction of a toile (a fitting sample). The toile is then used to determine further adjustments, which are transferred back to the paper pattern. This process, and the pattern created, can then be used as a template for tackling future fitting issues, modifying commercial patterns, or designing your own garments. During the workshop you’ll also be using scaled pattern samples to practice techniques. At the end of the course you’ll take away a completed comprehensive sample book on paper pattern adjustments, which can be used for future reference.

You’ll be using our in-house Fitting Pattern to create their toiles, learning additional techniques at each stage:

  • Cup size and bust adjustments.
  • Fitting the shoulders, including forward rotating shoulders.
  • Shortening or lengthening the bodice.
  • Determining the correct armhole size.
  • Rounded back and sway back adjustments.
  • Fitting the sleeve
  • Fitting the skirt
  • Pattern drafting techniques for designing a top, based on the adjusted bodice.

  • Cost of pattern
