Hand-Sewn Quilting Series II: Yeouijumunbo, 여의주문 (Cathedral Window)

A Virtual Class with Youngmin Lee

In Korean culture, yeouiju 여의주 means wish-fulfilling jewel, Yeouijumun 여의주문 means a jewel pattern, and Yeouijumunbo 여의주문보 is the name for a Jogakbo design that is found in the Joseon dynasty period (1392-1910) and in contemporary quilting. 

The first documentation of the use of the cathedral window in a quilt appeared at the Chicago World’s Fair in the US in 1933. The technique quickly became popular in North America in the 1930s. In her book, Cathedral Window Quilts, Lynn Edwards made the inference that this technique may have been brought to the United States from the East by missionaries in the early twentieth century. 

Each quilt block is made using a folded patchwork technique. This paper folding process is reminiscent of the folded paper fortune teller that many of us learned to construct in childhood.

Youngmin will teach students how to prepare, cut, fold, and connect units of fabric to create the base layer. She will then teach students how to embellish with additional squares of fabric and bakjwi maedeup (bat-figured knot).

This class is part of the Hand-Sewn Quilting Series II.

Perfect for the beginner and the seasoned quilter alike (and perfect if you’ve already joined our Hand-Sewn Quilting Primer Series), the Hand-Sewn Quilting Series II takes students on a journey of different forms of hand-sewn quilt construction, from Korean Yeouijumunbo to English Paper Piecing. Rooted in the diverse history of quilting and taught by contemporary textile artists, this series combines enduring quilting techniques with new voices and approaches. 

Beginners will come away with a newfound confidence in their quilting ability and a deeper understanding of the medium. More experienced makers will expand their textile horizons, as well as gaining new skills to use on personal projects. Experiencing the series as a whole is sure to provide a comprehensive foundation and will get you well on your way in a joyful practice of hand-sewn quilting.

The projects from each class can be combined into a sampler commemorating your textile journey or can be displayed individually as pillows or patches applied onto another textile. 

We hope you will join us for all seven of our quilting classes to experience new ways of quilting and broaden your knowledge of textile history. You can sign up for the entire series, or choose your own adventure by selecting the classes you’re most interested in.
