Historical woollen museum textiles present a particular challenge for technological reconstruction. Unlike newly woven fabrics, they have undergone decades or even centuries of wear, occasional washing, fulling, conservation and natural ageing. These processes alter the original fabric density, surface texture, dimensions and mechanical properties, making it considerably more difficult to interpret the original weaving technology directly from surviving museum objects.

The objective of this research is not simply to reproduce museum textiles as they appear today, but to reconstruct their original technological characteristics at the time they were first produced. Experimental reconstruction is therefore used to investigate the technological parameters that determined the original fabric, including wool quality, yarn characteristics, weave structure, fabric density, finishing, shrinkage, weight and overall fabric behaviour.

An important consideration throughout the research is that museum textiles do not necessarily represent their original appearance. Linen and woollen textiles change differently during their lifetime, and these differences influence the interpretation of historical fabrics. Linen garments were generally washed frequently, gradually becoming lighter over time, meaning that museum textiles appearing white today may originally have been woven from naturally grey flax. Woollen garments, by contrast, were washed infrequently, but were affected by wear, fulling, fibre ageing and long-term use. The objective of the reconstruction is therefore to understand how the textiles most likely appeared and behaved when newly produced rather than simply reproducing their present condition.

The research follows two complementary technological approaches that share the same objective: the reconstruction of historically accurate woollen fabrics for Estonian folk costumes.

The first approach begins with raw Estonian sheep wool. Fleeces are selected according to their fibre characteristics before being processed into yarn and woven into experimental fabrics. Raw wool selection and evaluation were carried out in collaboration with Katti Muru. The selected wool was then processed into weaving yarns by Muru Wool Mill, forming the basis for the experimental reconstruction of historical woollen fabrics.

The second approach begins with high-quality industrial wool yarns sourced from European spinning mills. This approach was developed primarily for practical reasons. Once the technological parameters of historical fabrics have been established through experimental research, the use of professionally produced yarns makes it possible to reconstruct historically accurate fabrics much more efficiently without repeating the entire fibre-processing sequence for every project. Both approaches pursue the same objective and are evaluated using identical technological criteria.

Experimental weaving forms the core of the research methodology. All experimental fabrics are woven using identical weave structures and sett densities, allowing the influence of wool quality and finishing to be evaluated independently of weave construction. More than thirty experimental fabrics have been produced, finished and systematically compared throughout the research.

Two principal groups of historical fabrics have been investigated. The first focuses on naturally brown woollen cloth for traditional coats, woven from undyed brown Estonian sheep wool. The second focuses on white woollen fabrics intended for traditional woven jackets (kampsunid), which would historically have been dyed. Colour reconstruction has intentionally been excluded from the research because surviving museum textiles display considerable variation in colour as a result of historical dyeing methods, ageing and conservation history. Instead, the research concentrates on reconstructing the technological characteristics of the fabrics, including weave structure, density, shrinkage, fulling behaviour, surface texture and mechanical performance.

Following weaving, extensive finishing experiments are carried out. Multiple washing, fulling and pressing methods are tested to investigate their influence on shrinkage, density, dimensional stability and surface appearance. Every experimental fabric is measured before and after finishing, allowing structural changes to be documented systematically. The objective is to develop practical finishing methods capable of producing reconstructed fabrics that correspond as closely as possible to original museum textiles while remaining suitable for contemporary production.

Throughout the research, reconstructed fabrics are continuously compared with original museum textiles. Evaluation is based not only on visual appearance but also on measurable technological characteristics. Fabric density, dimensions, shrinkage, surface texture and weight are analysed whenever possible. Museum textile weight provides an additional verification parameter, allowing reconstructed fabrics to be compared with the original material characteristics. This approach has demonstrated that modern reconstructions, particularly of woollen skirts, are often considerably heavier than the historical originals. Weight analysis therefore serves as an important tool for evaluating yarn selection, fabric density and finishing.

The reconstructed fabrics are further verified through practical garment reconstruction. Garment historical tailoring are carried out in collaboration with Merli Mänd, allowing the behaviour and performance of the reconstructed fabrics to be assessed in completed garments.  Folk costume master Kadi Vingisaar evaluates the reconstructed fabrics through their practical application in the making of Estonian folk costumes.  Experimental weaving has been carried out in collaboration with students from the Olustvere School of Rural Economics and Service Industry. Experimental fabrics were woven by Malle Avarmaa, Gerly Karu and Maie Ojamaa as part of their entrepreneurship placement at IIDA Studio. An additional ten metres of experimental coat cloth were woven by Rick Rohtmets during his practical training under the supervision of Eva-Liisa Kriis.

Rather than reproducing individual museum textiles in their present condition, this research seeks to understand the original historical weaving technology of Estonian woollen fabrics and to develop a systematic and practical methodology for their technological reconstruction. The aim is to reconstruct fabrics as they most likely existed when newly produced while making the knowledge gained through experimental research applicable to future reconstructions.
