Once you have a sewing pattern you like, it can become the foundation for infinite variations by using pattern “hacks”. A simple pattern for a pullover top can become a hoodie, a jacket, a dress, a sweatshirt, a tunic, a jumper, a t-shirt, a smock… whatever you envision. Add seams, gathers, flare, pleats, collars, cowls, hoods, cuffs, plackets, yokes, facings or other design details, and you’ll see that there really are no limits!

You may have drafted your own boxy top pattern in a previous class with Cal, or one of her online workshops, or you can bring a purchased pattern (listed below) to use as your starting point. We suggest that you have made at least one muslin or test garment from the pattern in advance, to confirm you are happy with the fit or size chosen. Cal will demonstrate a variety of pattern manipulation techniques, and then you can apply some of them to design one or more variations. Before you know it, you’ll have a closet full of handmade clothes!

Note: This is purely a pattern drafting workshop; we will not be doing any sewing in class.
