What kind of sock yarn? Would doublestranding be a possibility?<br>
You can do doodlepants using sock yarn, you'd just find your stitches per inch and multiply by that number instead of 5. Erika Knight's baby bloom has a cute pair of shorts knitted in sock yarn (first pattern in, with the chunky cashmere sweater) and leggings as well.
PM me with your e-mail addy. I have some VERY old vintage patterns that I'm pretty sure are now considered public domain that I can scan for you. They are written for "baby wool" and the gauge is pretty darn close to what I get with sock yarn.<br><br>
