About Bullion & Metal Thread Embroidery
Purl or perl (in English) and bullion (in French) has historically been used to add rich texture to hand embroidery. It is a traditional embellishment for ecclesiastical, military, ceremonial, and formal attire.
Purl is made from fine metal wire which is coiled into a spring-like spiral. It is typically cut into short pieces, using a sharp scissors, and stitched into place like beads, with the needle passing through the spiral�s hollow center. Sometimes these purl beads are stitched over padding. Longer purl pieces may be couched onto the fabric.
When working with it, remember that bullion is delicate. It�s easily stretched beyond its elastic limit, and after that, will not return to its original shape.
