I got a crochet kit for Christmas and I'm crocheting the poodle. Anyways I crocheted one of the ears and then it says to fasten off. It doesn't say to slip stitch but where it says 'Finishing a piece' it says to slip stitch, chain 1, cut yarn, leaving enough for sewing, and use the hook to pull it out through the next stitch. What do they mean 'through the next stitch'? Am I supposed to slip stitch again?
