Yes, it's true, but it's not really difficult. You knit the earflaps and break the yarn, but don't bind off. If you've got several needles of the same size I'd leave the stitches on the needles for each earflap. The take a needle that will be large enough for a hat and cast on (according to pattern) knit across1 earflap stitches and set aside the old needle, co x number of stitches, knit across earflap, co and then continue in pattern till you're done.
Now I know this sounds confusing. Just break it down into small bites. First do the earflaps. You can do it!
