Prices of shipping have gone crazy. I just sent one cross country via UPS and paid $28. The package weighed 10 1/2 pounds but UPS charges by the whole pound only. this also included $100 worth of insurance. But in my mind all quilts are priceless. What are the chances you could replace the fabrics used in the quilt?
I do like having on line access to track its progress. But I believe the USPS offers that as well. What about the one rate box? Seems to me you could easily cram this quilt into one of those and save a few dollars that way, but I'm not sure if they are trackable. So your choices are not a lot. Either way, I suspect you are going to pay close to $20 no matter what you do.
