When I unpacked the silk lining I ordered for $4 (plus shipping) from Shinei, I got a clearer idea of how a kimono is pieced together. The lining has two red stains (possibly where the outer fabric got wet in the rain and the color seeped). Shinei provides good photographs, so I was aware of the stains when I bought it. As this was just an experiment and I’m practicing on the polyester kimono, the stains don’t bother me.
However, I also got a bonus piece. Another inner lining in perfect condition which is the correct size for the polyester kimono since it has its hakkake (lower hem lining) in good condition. So, I’ll use the bigger piece for a sheer summer kimono I bought. Summer kimono are unlined and I’m thinking of using that fabric to make a skirt.
Bonus information. On the edge of one of the pieces was stamped グンゼ絹ばら(Gunze Silk Rose) . I looked that up and learned that Gunze is a famous fabric manufacturer that started as a silk factory in 1896. And “Silk Rose” was one of their trademark brands.
I also found this blog post which decried the unavailability of the Silk Rose brand these days. It also mentions that it is purported not to shrink when washed. I did a wash test on the collar piece and it seemed okay.
