I've sent over 25 quilts thru the post office in the last 2 yrs. NEVER had a problem. I do NOT put on anything that it's a quilt...........the few times I've gotten insurance, I said it was "fabric".....
I just recently sent a king size quilt from Bend, Oregon to Yuma, AZ for less than $20.00. '
Oh - I had advice from a friend when I started sending the quilts ------ I NEVER take the boxes to a store that sends it for me. I got directly to the Post Office. Just saying.....................
