Etsy

If you like to buy items made in the US, Etsy is a great resource.
I have purchased several items from Esty including two purses, a wallet, a dog collar, a shirt and a wooden spoon, all made by artists and craftsmen from the United States.
The sellers are not limited to the United States. I also bought a fun iPod case made by a lady in the Netherlands.
You can find tons more things on Etsy as well, including jewelry and furniture.
Want to buy things locally? Etsy is great for this. You can narrow your search to items near where you live by using the Shop Local link, and you may even be able to pick your items up rather than paying for shipping.
Concerned about wastefulness? You can even find vintage and upcycled items on Etsy.

Those pesky unmentionables

The year we celebrated Christmas with only gifts made in the US, I ordered my husband some Wickers brand underwear, which we had not been familiar with before. They were a huge hit!
Wickers uses a silky moisture-wicking fabric and they make underwear, t-shirts, thermal underwear and more for men, women and children.
I've bought them from both Sierra Trading Post and Wickers web site, t-shirts and underwear both, and we've never been disappointed. If you sign up with Wickers email list, you can receive notices about sales.
