I thought this was interesting and wanted to share, my friend uses Tyvek, (the stuff you wrap the exterior of a new house with) for the purses/bags she makes, she said it is really sturdy.

She will stop by construction sites and ask for some of their scraps, pretty thrifty idea.

what a good tip, thanks.

Does she use it like fabric?

pretty smart, especially for lunch totes (insulating)

That is so cool. And I can see the construction guys all across America (the world?) wondering why all these women are asking for their scraps!!!

Sounds interesting. How exactly does she use it? Is it used for stiffening, sewn to the back/inside of the fabric? :thumbup:

Anyone know if it can be machine washed?

Isn't that the same thing the Post Office free mailer bags are made of?

Tyvek is used for practically indestrutable envelopes that FedEx uses and probably others. It is waterproof, but gas permeable. Because of it characteristics, it is used in the medical device industry for much of their packaging needs when product sterlization is by gas (ETO).

Very versatile material. Love the bag lining idea! Especially for free!

Yep, the soft (not flat rate) Priority Mail envelopes are made of Tyvek. And they're free. One envelope should be enough for one bag. And lots of other neat stuff.
