The Geometry of Sleeves: Set-In Sleeves
Friday, April 16, 2021
10:00 AM - 12:00 PM

Session Type:
2-Hour Class
Skill Level:
Natalie Warner
Design, Garments, Knitting
Class Details:

In this class you will be introduced to the principles for drafting a set-in sleeve. With contextual examples, reference to body measurements, and demonstration from Natalie, you will be guided through the process of drafting a sleeve to fit the armhole and the wearer, shown how to check the fit of your sleeve head using a calculator, and receive pointers on finishing directions.

Part of the advance reading will include notes on design and styling for those interested in creating their own garment patterns. For those who attended, this will include a recap of the sleeves lecture given during October 2020’s Virtual Knitting LIVE! You do not need to do any knitting in preparation for this class, but you are welcome to bring along your own projects, use your personal body measurements for calculations, or refer to an existing pattern to support your learning. And afterward you can have a go at knitting a mock-up of the pattern you draft in class!


Read over the handout, which will be posted the week of class.

Supplies for Class:

A scientific calculator (like the one in your phone). Please make sure that your calculator has parentheses/brackets, pi and trigonometry functions;
Pen and paper for note-taking
Pencil and ruler for drafting. Any pencil is fine, but a mechanical pencil is best because it will stay sharp.
Squared or grid paper for drafting, A4 or letter size. If you are working in inches, you will need to get quarter inch (quad or quadrille) paper. Four boxes on this paper should total one inch. If you are working in centimeters, your squared paper should have boxes that are 5mm by 5mm, so that two boxes total one centimetre. If you cannot get hold of a pad of this paper, here are some links so that you can download and print at home:
