Sewing patterns

[juandr-92]

Can I ship sewing patterns regular 1st class mail if they are not very thick

I believe first class mail is limited to 1/4 inch in thickness.  If thicker than that, then you will need to use Ground Advantage.  If you ship first class mail, there is no tracking.  If the buyer claims non delivery, you will need to fully refund item price + shipping.
