This tangerine orange ric-rac from la Stephanoise in France is beautiful, and it's also 100% cotton! The total height is 3/8" or 10mm, and the centre of each bump is 1/2" or 12mm apart.
This trim is sold in half yard increments: one unit equals one half yard. The ribbon will be cut in one continuous piece regardless of how many units you order (i.e. if you order 4 units you will receive a single 2 yard piece).
