Pattern Alterations: Full Bust Adjustment



The dreaded 'FBA'! - Full bust adjustment.

If you are using commercial patterns such as paper patterns and PDF patterns, you will have noticed that all patterns are usually drafted to a B or C cup.

If you are smaller or larger than this drafted cup size, you will need to do a 'full bust adjustment' on the pattern before you cut your pattern out in the fabric.

This can be a very daunting task, especially for beginners.

During this workshop, your host will teach you two different techniques that will cover a princess line bodice style and also a full bodice with bust darts.

Workshop Breakdown:

1. Size charts - choosing the correct size to use as a base
2. Taking body measurements
3. Understanding cup size and how this will alter your sizing and pattern
4. Differentiating the front body pattern and back body pattern
5. Creating an 'FBA' on a full bodice with darts
6. Creating an 'FBA' on a princess seam bodice

You will work on blocks/slopers that are your base size, manipulating them into your personal cup size. You will then be able to transfer this knowledge onto all your patterns at home.

If you would like to bring any patterns you would like to bring, for advice, we will have a 15 minute Q&A session at the end of the workshop.

This workshop is suitable for 16 years and above. All students under the age of 17, must be accompanied by a participating adult
