The Tip
Tipping is the material used to finish the backside of the tie’s end. It’s machine-stitched on and typically goes up three to four inches, but on some ties, can go as high as the knot (though that’s rare and makes for poor construction). If a tie is said to be self-tipped, it means the tip is made from the same material the envelope has been cut from. When a tie is untipped, the edges can either be sewn flat or hand rolled and hand sewn like the edges you would see on a nice pocket square. If the tie has hand rolled, hand sewn edges, check to see if there are wrinkles or dimples on the front of the tie. If there are, the sewing was done too quickly, and a mark of lower quality craftsmanship.
