Heather Kojan: Half Square Triangle Master Class (Half Day WS, Fri, 9/12/25, 9am-12pm)

If you are taking a workshop with sponsor-provided Baby Lock sewing machines, you must use the sponsor-provided machine and may not bring your own machine to class. A portion of these workshops may contain sewing machine product information.

This skill builder workshop is focused on the most versatile building block in a quilter's bag of tricks, the Half Square Triangle. Explore ten different ways to make Half Square Triangles, learn the math behind it, and play with a collection of tools to help make these units quickly and accurately. This workshop sets beginning quilters up for success and opens a world of construction methods for advanced quilters!
All Levels

Required class kit, $20 payable to the instructor in class, includes Quilt Pattern, hand out, a variety of foundation piecing papers, Quilt in a Day 6 ½” Square up Ruler.
