Natural beige lacey collars, these look like crochet but are actually a kind of cotton lace. They come joined together in a pair which you snip apart yourself. The size is quite small and probably meant for children's wear - the inner length of each side is about 18cm. It can still be used for a lady's top, as long as you don't mind the two back ends possibly not meeting in centre back, or attach a chain and use it to make a necklace.
Other trims shown are available in the shop under the "Notions" section of the menu.
