KREINIK-Kreinik Blending Filament. This is a 1 ply metallic thread that may be used alone or combined with other threads and yarns. Perfect for enhancing needlepoint, cross-stitch, and embroidery designs. Blending Filaments are also popular for punch embroidery, lace-making, weaving, knitting, and crocheting. Blending Filament is a flat fiber so additional dimension and light can be added when the filament is allowed to twist on the surface: also called Balger. Soft and easy to use these threads are hand and machine washable. This package contains one 55yd/50m spool. Made in USA.
