Folk songs, customs, traditions, national costumes are part of our history. They are priceless treasures that define us as nation. It is our duty to keep them sacred and pass them down from generation to generation. The work presents the results of the research of the techniques of ornamentation of handmade products, textiles, fabrics, leather and accessories from the area of Bessarabia. Special attention was paid to lace and the correlation of the crochet motifs with embroidery elements. Lace is a decorative element of the interior of the house, but also a garnishing element of the popular shirt. It is considered to be one of the oldest decoration techniques with considerable revival and appreciation in the 15th century when it is used to decorate royal and noble clothing. In the folk costume, lace is made with a crochet hook and a needle with cotton or silk thread. If the embroidery ornaments in the folk costume are in colors, then the lace is made in white. The study was carried out on the basis of the popular costume, the towels from the interwar period of the 20th century. The results of the use of information technologies in the preservation of these ornaments are also presented. The purpose of this study is to present the stages used in the identification and revitalization of the ornamentation techniques characteristic of our country, to identify the methodology of preserving the traditional ornaments used in the Republic of Moldova and to propose directions for further use.
