Debbie Maddy is a designer, teacher and founder of Calico Carriage Quilt Designs.

She loves fabric, sewing—and quilters and designs patterns for quilts that are visually stunning but easy to make. Since 1993, she has shared her enthusiasm for quilting with others through teaching and in  2013 and 2015 was a nominee for Teacher of the Year by the International Association of Quilting Professionals.

In her simple, accurate No Diamonds / No "Y" Seams technique, there are no fussy bias edges and all the quilt assembly is done with straight-line sewing. Instructions are written in an easy-to-follow style, with cutting, layout and piecing diagrams to ensure success. Using her patterns, novice quilters can confidently make beautiful old-style quilts, while experienced quilters can enjoy fast, easy piecing with striking results.
