I tend to forget how intelligent my husband truly is. If you lived with a man who suffered from GBB, you'd forget too. And really, how often can you tell someone not to wear two prints at the same time before you start thinking he's not the sharpest knife in the drawer?
However, the other day, when I was telling him about the socks I was making for our friends' baby (who was born in July or there-abouts), and complaining that I didn't know how big to make socks for a 6 month old, he came up with a simple answer. Look up pediatric growth charts. This was incredibly brilliant, but alas, they only have length, weight, and head circumference on those things. But, in my travels, I did find a chart for baby foot sizes on a website for shoes. According to Shoofly, a 6-9 month old baby needs a shoe that is 5 1/8 inches in length. This seems a little long to me, but what do I know? The sock I finished is just under 5 inches in length, heel to toe, which should probably be okay. Really wish I had my own baby to compare to. The second sock is on the needles and will likely be done by the end of the week.
I usually knit socks on 2mm needles using fingering weight yarn. This generally means they take quite awhile to make. Like months. For Christmas, I've made socks with sport weight yarn on US4 needles and those just fly by! I do like how the stitches look at 9.5 stitches per inch, though. So tiny and perfect. No floppy stitches, just nice and even.
However. I'm not sure I want to devote the next three months to making these socks. So, I started swatching the Cabin Cove yarn using 2.5mm needles. I don't have enough done to get a good stitch count, but the stitches do look bigger.
