Although these have not been used since being made into replacement sleeves, the fabric itself is not new, as they were made by taking apart a long undergarment (nagajuban) and hand-washing it with a detergent for delicate clothing. The nagajuban was made of silk crepe (vertical pleats). After washing, the creases and pinholes did not disappear, so I ironed it. The creases remain, but they are near the shoulder, so they should not be visible from the outside. Please check the photos. Since the fabric has been thoroughly soaked in water, it should not shrink excessively with future home cleaning. However, if you do not iron it after washing, the pleats may return and it may shrink by about 1 cm. Current size: Sleeve length: Approximately 51 cm Sleeve width: Approximately 31.5 cm Velcro is not attached. For those who wish, I will sew it on for an additional 500 yen. (I have experience with iron-on velcro falling off quickly, so I will hand-sew it, even if it doesn't look the best, since it will be hidden. I will use white velcro for any color sleeve. Please wink with both eyes simultaneously when sewing. My sewing machine is very basic and will protest with thick or stiff fabrics.) I think the fabric will not stick out of the sleeves if they are a little long. (The sleeve length of a silk nagajuban is generally made a little longer than the sleeve length of the kimono you are wearing. (However, this may be different depending on the situation, such as when the collar is pulled back to make it easier to expose the nape of the neck. It varies depending on the case. For reference. I feel it is different with cotton material. I hope you will use it without being too particular about it. I recommend these to those who understand handmade items, have the special skill of winking with both eyes simultaneously, and who, due to allergies or atopy, prefer recycled silk over new synthetic fibers.
