Polyester thread Original threads by tie design  Email me for any other color requests if you have sensitive skin and stitching bothers you, feel free to let me know so I can iron on a soft backing for you! Heads up - This listing is a PREORDER, meaning that shipping will take 4-12 weeks. It might be sooner but I have to order your size and then make it so the process is a little longer. Thank you for your patience!
