Two large remnants of a shiny satin-like fabric but I'm not sure what it's actually made of. Greener than it looks in the photo (closer to the colour called Jade Ivy on https://www.shutterstock.com/image-vector/jade-color-palette-guide-names-catalog-2495994219?trackingId=8d60f30f-e9e1-4619-83ed-89d8604ea61a&listId=searchResults) . Irregular shapes but one piece would give a rectangle of about 40 by 40 cms, the other a rectangle of 75 by 65 cms. I can try to get a better photo if you are interested.
