Tiny tutu
When I quit smoking I was knitting obsessively so I wouldn't run out and buy ciggies (it's been 3 years now!). So I found a book called Knitting for Dogs. There were these cute little tutu looking sweaters in fuzzy yarn. I found some adorable confetti cotton tape style yarn in the clearance bin at JoAnn's and bought about 20 skeins at least. I made over a dozen chihuahua sized tutus in every color combination I could. I have sold 8 so far.
