I swear by the new "Flat Rate" boxxs from the post office. you can leave the postal guy a note to bring you some various sizes. And it doesn't matter how much you can manage to squeeze into the bax it's a flat weight. I have figured out to send fabrics and even roll them in a tight ball to fit them into every nook and grannie I can find. Actually I have the rates, which are in the other room right now for box postal costs. The postage gives uyou the boxes for free, As long as you don't use the paper bag version of priority male, you can save a fortune. Then it's up to if you choose to seel to include the postage. Go to www.usps.com and play around in there. Saves a bunch of money if you ship a lot of stuff.
