Cynthia, the really good thing about the Toirneach Kilt Hose (you can see the pattern in the 2007 Winter Issue of Knitty-www.knitty.com.) is that they are made to measure. You adjust the size to the measurement of the wearer and the only complicated (but it isn't) part is the cuff. A few minutes of careful measuring will give you some very nice kilt hose that don't bag or sag! Another plus is that they are knit on size 7 needles with a fairly substantial yarn that isn't tiny like most sock yarn...and you won't lose your stitches on DPN's that large. Of course, if you're able to master it, they can be knit on circular needles. Sadly, I have yet to learn this technique, but it's on my list of "must learn" before the end of 2009!! Another thing you could do is knit a fancy cuff on a pair of store boughts, but to me that just takes away from the fun of knitting the whole project.
You could also check out your LYS or Knitting Guild for help if you do get stuck.
