The runner has an interesting “star” design, but I am no expert in design so it could be some sort of flower.
There are no noticeable stains as far as I can tell. Please see the multiple photos for the exact conditions.
I inherited this runner from a great aunt, so its age is probably in the 80-100 year range.
I hate to give up this vintage item but now it’s time to sell it to a deserving buyer, so I can clean out my closets one item at a time = : > )
