Sandra Bruce's "Wake Up Cup" and Material Matrix Technique



Sandra's technique, "Material Matrix", is inspired by the painter, Chuck Close. It involves using a gridded photograph and interpreting each 2-inch square into fabric, using piecing to achieve the effect. The finished size of this project is 16"  x 20".

This is a 2-day workshop where you will make “Wake Up Cup” and learn how to use Sandra's technique. If you enjoy piecing you will be happy here! Covered in the 2 days will be: how to do Sandra's technique, exploring color and value, gridding your own photograph, what makes a good photo for this technique, and how to make a matched binding. You will learn how to “see” in a new way, and increase your piecing skills. You will be able to finish it at home, with the handouts Sandra provides and the knowledge you receive during classroom time. 

Sandra will teach for 6 hours each day. We will take a 30 minute lunch break each day.  Bring your sewing machine and your lunch.
You may leave your equipment set up overnight at the shop, for this two day class.

Sandra has been featured in Quilting Arts Magazine and Quilting Arts TV. She has taught a Empty Spools in Asilomar, California.

You will need a fair number of different fabrics and few other supplies from home. Please download the attached supply list. Preparation is minimal - do not cut fabrics.
