his self-tie emerald and navy bow tie is made from double sided silk twill 12. As it is double sided there is a different pattern on either side. I used emerald and navy steam fix dyes. I then put salt onto the wet dye. When heat is applied the salt pulls the dye into a unique pattern. The bow tie is steam fixed so it is hand washable. Washing instructions are included. It will brighten up your evening/formal wear. Each silk bow tie is individually hand dyed so patterns and shades will vary.
