it can be intimidating. I'd first recommend letting the capelet set in the freezer for awhile as that makes it easier to frog mohair. Then take a tapestry needle and some smooth yarn and just run it through the stitches a few rows back (shoot for the purl drop row, it'll be the easiest to snag) then just rip back with confidence knowing that you won't be able to drop any more stitches.
Plus, lace hides a multitude of errors. Especially gorgeous funky lace like in this pattern.
