Abstract
The combination of an electronically controlled sewing machine and an auxiliary memory comprising pages of a book, or the like, each page having optical bar coded stitch pattern data printed thereon and in obvious association with a graphic representation of the actual stitch pattern. The coded data is sensed by a hand held optical reader which transfers the data, for a desired stitch pattern, to internal memory of the sewing machine.
