there are several cast ons that work --you can use any single yarn cast on!
Single yarn cast on's include:
crocheted (not provisional but a version of knit on using crochet hook)(sally mellville, in the Knit Stitch book, has directions for this..(and they are else where))
there are advantages and disadvantages to each of these cast ons, which one you chose is your choice.
for many, the choice comes down to which ones they know!
I personally like the simple twisted. (the base half of the norwegian twisted long tail!) its simple, and neater than a plain simple.
