Vintage set of matching crochet table cloths diamond shape

3 piece set of old, vintage matching crochet table cloths or covers. These 3 matching pieces are diamond shaped in a dark cream and the material is a bit shiny, possibly a silk blend? Hand made, crocheted in a 6 petal flower or snowflake, with a double layer rosette in the middle. I see 1 darker spot on one of the small ones (review last pic), I have not cleaned them bc I'm too nervous but may come clean with a soft spot cleaning. This is for the matching set of 3. 1 larger approx 41in x 25in 2 smaller ones approx 17in x 12in
