Flowers of the Needle is available as a free download from Kathryn Goodwyn‘s Embroidery Page. Kathryn says,
This is a revised edition of the original of 1985, which went out of print in 1992. Years of persuasion by others finally caused me to scan and digitally remaster the work. Flowers of the Needle is a compendium of seven Italian needlework pattern books of the 16th century, from 1531 to 1567. It is a treasure house of linear (i.e. “free form”) and charted patterns, originally intended for a variety of uses by both professional and private needleworkers.
