371 thread, marcasite 371 thread, marcasite 371 thread, marcasite Goldwork thread for embroidery projects £2.50 Quantity: at £2.50 each Add To Basket A black core thread wrapped with a fine dark silver filament for goldwork and embroidery projects. This marcasite 371 thread is finer than Japanese thread and more like a fine passing thread. To use, couch down with a strong sewing thread at even intervals (about every 2-3mm) in pairs. The ends will need to be 'plunged' through to the back and finished off (see goldwork video 4, here). This item is for 2 x 3m lengths (allows you to couch over two strands together). Please note there is no gold content in this product. Also available in other colours!
