Last year, my favorite Christmas stocking gift (besides the candy) was a set of stainless steel drinking straws. I'm a committed straw user, and I love that I can simply wash these and use them indefinitely...plus the experience of drinking a cold beverage though a chilled, heavy straw is...I dunno, pleasant.
Many of my straw-hating friends and family even took to them, preferring the experience over the sensation of thin plastic in their mouths, so I looked into buying some more...and they're like $7.00 a piece. UPDATE: The site that hosted the original project is no longer live, so ManMade came up with our own tutorial for making DIY metal drinking straws. Check it out!
