Another distinctive feature of Tual collection is its finishing touches, including the lace which originally is a Turkish handicraft dating back to mid-1500s.

Turkish Lacework, 'Oya', is one of the most elegant examples of a variety of the rich Anatolian (central Turkey) Handicrafts. Basically described as a thin lace, 'Oya' is a handicraft applied with tools such as needles, shuttles, crochet-hooks, pins; using silk and cotton threads and sometimes with additional accessories like spangles and beads.

Being a unique and truly Anatolian Handicraft, there is no name or direct translation for 'oya' in other languages and therefore it is simply and commonly referred as the Turkish Lacework. The oldest examples of 'Oya' that were found in the Menfiz excavations in 1905, suggested that this art dated back to 2000 BC. In some sources, it is stated that this type of lacework went first to Greece and then, via Italy, to Europe in the 12th century from Anatolia.

For the Anatolian woman 'Oya' is a way of expressing herself. She transforms her thoughts and feelings into colors and motifs loop by loop. Eventually this unique piece of art becomes a tool for talking without words and conveys messages. For example, if a young girl is in love she wears a headscarf with purple hyacinth 'Oya' around; if she is engaged she wears the one with pink hyacinth. Yellow carnation expresses longing, yearning and sorrow. Rose 'Oya' is mostly used on the bridal veil. Pepper spring is the 'oya' of the bride who does not get along well with her husband. When the family of the groom sends the bride a headscarf with roses, they say that she is welcome in the family.

Besides flowers, there are 'Oya's which have names inspired by vegetables, fruits, animals, daily life, events, people and material around.

'Oya' is one of the most distintive features of Tual collections.
