Foldover elastic has a line scored lengthwise down the middle, so it folds over neatly and easily. Typically used in making inner wear - to enclose raw edges such as at the waist and leg opening of undies, or the upper edge of bralette cups. These are thin - less than 1mm thick. Not suitable for applications such as elastic-waisted pants or skirts. To preserve the life of anything with elastic, avoid washing at high temperatures or tumble drying.
Last photo shows the 14mm camel FOE used to bind the underarm/upper back line of a bralette (fabric used is a 128gsm modal also available in the shop, and the white picot edge elastic used as the bottom band is available here).
