I feel for you.
I would give it a few more days before starting a new one. It might just be delayed.
I sent a quilt to a friend about 8 years ago and it never showed up. Has never been seen since either. After that loss, I made sure to include both addys inside the box and I now use a mailing bag with the information listed on it too inside any box I send. I'm not willing to lose another quilt that way. Oh and I make sure to have delivery confirmation too.
