the post office gives tyvek envelopes. I had a clerk put my envelope into one since she thought it would work better!

Slide the material between paper, put into plastic and into brown envelope and ship "Book Rate:. It is the lowest rate possible. I have been shipping quilting books and they are heavy and run about 2.20 to 2.70 to ship.

Don't get caught using media mail or library mail rates to ship anything but that which is allowed. The fines are huge!

Also, poly mailers are stronger, more waterproof, and cheaper than tyvek envelopes, but if you want stuff to be truly waterproof, a sealed inner bag is necessary. Ziplocs are a cheap alternative if you're not shipping a lot.

A good place to get shipping supplies is www.uline.com.

I can get the bubble envelopes at Dollar General and even the dollar Tree store.

I try to always mail mine in a zip lock bag and enclose the intended address in it. That way if the envelope is destroyed they still have the address.

I buy mine at Wal-mart as they have a good price and variety. I have several sizes available at all times. Sometimes I am able to recycle what has been sent to me.

Any office supply store will have a variety of envelopes for you to choose from.

I only use the bubble ones if I have something likely to break. Otherwise I just use the ziploc bag inside a regular Kraft envelope and use plenty of packing tape to be sure it seals well and the address is protected.

Mostly I try to reuse ones I've received in the mail.
