I don't know the details, but I believe the orange (a muted orange) is silk, and the light green one is likely synthetic fiber. Orange: It looks like a piece cut from a襦袢 (undergarment), with thread remaining. It's 27cm x 130cm, folded in half and sewn in the middle. There are some damages in places. Light Green: 35cm x 90cm. It has gold and silver dye, and gold thread embroidery. There is overall soiling, including dirt on the fold lines. #KimonoScraps #JapaneseGoods #SmallJapaneseItems #OldFabric
