Margaret Holzmann is the author of the hugely popular Geometric Knit Blankets. She likes to design and knit the BIG things: blankets, throws, and sweaters. She uses these larger items as a canvas for color work, shapes, and texture. She excels at construction techniques, the geometry of knitting, and color theory. Following a career as an engineer at Bell Labs and Jet Propulsion Laboratory, she is now a full-time knit designer living in Monrovia, California, and her patterns have appeared in many knitting publications.
