It's a hobby that brings Sam Barsky all over the world. It's also gone viral. Sam started knitting for fun in 1999 and soon made his first "picture" sweater, all without the use of a pattern. Now, Sam has made more than 100 sweaters, and the fun part is that he has traveled to many of the places and landmarks depicted on his work. Sam also designs sweaters with his favorite things. We can't wait to see where he goes next!
