Dear Serge,
Neckties was one of the first projects my accessories students made in class. We used old ties that were dirty, had holes, but were the type and shape that the individual student wanted. We took them apart, saved the the wool fleece from the inside because we are in a rural area and cannot find this type of fleece. You probably won't have the same problem, but if you do, the wool fleece in the ties is just the right size. Observe how the tie is put together--that's just how you should do it. Carefully press the facings at the ends of the tie, and press the tie out flat. When you place it on your new fabric, make sure that the grain is exactly the same as the sacrificed tie. The facings can be cut from rayon or silk lining fabric. I prefer silk. Or if they're in good condition, you can use the facings you removed. Sew the facings to the tie ends. Do not sew the sides of the facings. Do not trim, but miter the ends, just as the original tie was mitered. Turn the facings right side out and carefully press. Next, with the right side facing your ironing board (or other padded surface), place the fleece on the wrong side, just as it was in the original. Press in 3/8 inch on one long side of the tie. Fold over the other side the entire length of the tie, including the faced ends. At this point, you want to make sure that the ends are perfect points before you press. When you're satisfied, press down the unfinished edge the full length, then fold the other end over it and press it. The finished (pressed under) edge should be centered on the wrong under side of the tie. You can pin now, along the center of the under side of the tie. As you can see, this is more a pressing operation than it is a sewing operation. It will take you less than an hour to complete the tie. Now, hand sew with a slip stitch this center seam, occasionally catching the fleece to hold it in place. You're done. My students used all sorts of fabrics for their ties, not just tie fabric, which is impossible to find anywhere around here. Have fun!!
