What you’ll make
Create new garment variations by transferring a neckline, armhole and sleeve from one sewing pattern to another compatible base pattern.
The first example starts with the Erika T-shirt, raises its neckline using the Irún Sweater pattern, and adapts the Irún armhole and long sleeve.
The second example combines the Riley Dress with the neckline from the Turtleneck Sweater and the armhole and sleeve from the Calella Sweatshirt.
This is a paper-pattern modification class. You will work from patterns you already have, using pattern paper, a ruler, and pencils or markers to distinguish the new lines.
What you’ll learn in this class
- Trace a base pattern before altering it.
- Raise or lower a neckline using another pattern as a guide.
- Transfer an armhole so it works with the corresponding sleeve.
- Repeat armhole changes consistently on the front and back.
- Check shoulder lengths and adjoining lines before cutting.
- Assess compatibility in ease, proportions and fabric behavior.
- Test an altered neckline or sleeve area in sample fabric.
Choosing compatible patterns and fabric
Choose patterns with similar ease and proportions. A close-fitting body is not a natural match for a very low, wide armhole and an oversized sleeve.
Fabric type also matters. A woven pattern may work in knit fabric, but a close-fitting pattern intended for stretch fabric may not provide enough movement when sewn in a non-stretch woven.
Make it your own
Use the method to open or close a neckline, exchange a short sleeve for a compatible long sleeve, or combine selected details from several patterns.
Make a partial sample of the altered neckline, armhole or one sleeve when possible. This lets you assess the combination without sewing the entire garment in your final fabric.
