Welt – The welt is knitted first on the machines and is a double layer of nylon. This is the part of the stocking where the suspenders are attached and needs to be more robust than the rest of the stocking. Genuine vintage stockings frequently have writing printed on the welts which adds that extra touch of authenticity and the stockings should be worn with the writing on the outside of each thigh.
Shadow welt – This is a single thickness of welt – a lighter transitional area between the darker welt and the single layer of nylon found in the rest of the stocking. This is also known as the Underwelt.
Keyhole – The keyhole is a decorative bi-product of the manufacturing process but please be warned – it is not robust enough to support suspenders so do not clip them through this hole!
Seam – As previously mentioned, this binds the stocking together. Fully fashioned stockings can be easily distinguished from modern seamed stockings by examination of the seam. If it appears to have been printed on or sewn on unnecessarily, it is merely a decorative seam.
Compression stitching – This is a row of needle marks equidistant each side of the seam formed during the seaming process.
Heel – The heel is designed to reinforce the sole of the foot and comes in many different designs (see infographic above). 'Point heel', 'Cuban heel' and 'Havana heel' are perhaps the most popular stocking heel types, followed by the 'Manhattan heel'.
