    Item was a slight shade lighter than the pattern listed. Evidently, it was a pattern that was identical and very close to the color of the one listed. Totally, hard to tell unless the colors are side by side. Seller kindly helped me figure out that it was not the pattern I was looking for. And very graciously offered free return shipping and reimbursement. Great communicator and highly recommend this seller.

    Item was received and in good condition but it was the incorrect size. Reached out to vendor and they sent out a replacement. Unfortunately it was also the incorrect size. I only give it a 5 star because the item was refunded and the vendor was apologetic and I was allowed to keep both items. Things happen sometimes😊. Both items will just be donated.
