Sew-on Stones are loose crystal elements that can be sewn by hand or machine onto any type of textiles or accessories. Sew-on Stones come in two- or three-hole varieties and can be used for a range of decorative purposes or for fine embroidery. Lochrosen are crystals with just one hole (similar to a sequin).
They have two advantages over glued crystals (hot fix/no hotfix flat backs). Firstly they are more secure and secondly they allow garments to move more naturally and don’t stiffen the fabric.
