Set of 4 braided chair pads in blues and creams

This set of braided rug chair pads in a dark blue, light blue and cream is in excellent condition and made in the US (see pics for tag), age unknown, but likely 70’s colonial revival. 3 of the pads have two ties for securing to chair back spindles, one pad has only one tie, and one tie has a knot to lengthen/repair it. They’re likely acrylic/polyester, definitely not 100% wool, and have been machine washed and line dried. They’re 13” round and thin, and have a nice, vintage vibe. No rips, snags, tears, holes or other damage (except one missing tie and one repaired tie), the ties are navy blue acrylic and thread through the stitched pads. More pics or info on request.
