Vintage Fabric Retro MCM Rayon Blend? Navy Bright Geometric Flowers 1980s.

This fabric is in vintage new condition. From the 1980s my best guess is based on other crafting and materials found in this estate. No rips no tears no stains no smells. It is a silky material although I'm sure it's a rayon polyester cotton blend of some kind but that is a complete guess, the fabric is unmarked. It's very shiny and silky on one side and dull on the other side. It measures 38" wide total (not folded in half) x 4 yards. Please see all pics
