I've finished the pair of Araucania socks for my mother. In the photo at left, you can see where I ran out of matching reinforcing yarn just before turning the heel. (Click on the photo to see a larger version)
The difference in color is subtle enough that you can only really see it up close, as in the photo at right.
Mom just loves them, and is so happy to be able to switch off between the 2 pair of handknit socks I've made for her.
I couldn't let the 4-year-old feel left out, of course, so I made him a quick pair of thick socks in some leftover worsted yarn (Patons Classic Wool) to wear around the house as slippers.
I also made a little outfit for the baby doll with some of that grab bag yarn. I don't know what the yarn is, but it feels like a cotton and synthetic blend. The pattern comes from an old Patons booklet of doll clothes. The doll itself was made by my mother from a pattern by Judi Ward called Bare Baby, and you can find it here. It is rather lifelike, and all the kids just love to hold 'the baby'.
