Alex is wearing the hat, scarf and mitten set I knitted on my USM last winter, 2005. You can see the mittens in the picture on the left, you can also see that the hat was a little bit too small. The picture below shows the colors in the yarn on the scarf. This is Red Heart Kids crayon color but Grandpa has a matching scarf and he's no kid, well maybe at heart :)
I just realized that the yarn matches the Tide boxes behind him LOL!
