A sudare can look like a simple repeated set of narrow members. Tokyo’s technical account makes the repetition more specific: preparing a bamboo strip differs from sorting reeds and other stems, and orientation still matters when weaving begins.
Technique and structure
For bamboo, the reference describes coarse splitting and hegi work with a nata, followed by finer splitting and shaving with a small knife. For the other named materials, sorting considers thickness at the ura, middle and moto parts in relation to the intended product. After correcting the material’s set, the maker alternates ura and moto while weaving to keep left and right even. The regular surface is thus not just a choice of weave pattern; it also reflects selection and the direction in which the members enter the assembly.
A blind is not a basket specification
The listed materials include bamboo, reed and hagi, among others. The source also names several weaving approaches, rather than a single construction for every sudare. These distinctions make the material and weave useful parts of a product description.
An even-looking sample does not reveal the dimensions or installation requirements of a different blind. A made-to-size enquiry needs the actual opening and intended placement.
For international readers
Ask which material, weave and fitting method are proposed for the intended location. The process reference provides no quantified cooling, weather-resistance or privacy rating.

江戸簾：素材の太さとウラ・モトの向きを揃える
江戸簾の技法資料では、竹をなたや小刀で割って削る工程と、ヨシなどのウラ・中・モトの太さを選別する工程を分けています。編む際には素材のくせをため、ウラとモトを交互にして左右を均等にします。均一に見える簾を、編み方だけでなく素材選びと向きから読む解説です。
